You did but our car does not have gauges so this is not the right one per Solb44's photo, correct? Also, the original engine block was found with this angled fitting still in it albeit angled wrong.

We are not sure of the changeover or plant variance either but I have had a few people send me photos of their survivor cars showing the hoses and special clamp without the vent exactly like our car is so there was obviously two different designs at one time. I will be restoring the car exactly how it was found at 19,000 miles.

I did not send them directly to you - If I recall I forwarded them to you via Woj. If I recall Woj's words exactly: "I will be the clearing house for all technical information on this Nelson project?" ...or something to that effect! ;>))

SS427 12-06-2018 01:08 PM

ah ha. Got them but seems to me they were a slightly different photo. Thanks for sending them regardless. Everyone who has been helping me with this project is much appreciated. I think I am wearing out my welcome with Phil though. ;) He has been great and am about ready to make the 10 hour drive to go over his car. I tried doing it at MCACN but that was a wasted effort as I was only able to ever see 5 cars in two days.

JoeC 12-06-2018 01:10 PM

did your car have the Yenko installed SW gauges - oil amp watertemp?
there would be holes for the gauge panel and holes in the firewall to run the lines.

I don't think Yenko used the oil pres sending unit when the SW gauges were installed

Chad's Yenko was equipped with the aftermarket gauges so he had the plastic line (as seen in the upper left corner of the photo). Unfortunately my photo from that time is lousy and does not show the fitting at the block. Our car had no extra gauges other than the pedestal tach. The only holes in out gauge panel were for the tach. It is odd how our fitting was turned down though the engine had been worked on so who knows.

ScottG 12-06-2018 02:36 PM

Rick, the body and paint are excellent so far. Your suspension and chassis work is very high level also. That is going to be an outstanding car!

I only have a 1969 Assembly manual so I'm not sure about other years. It only shows the set up with the plastic vent.

I'm not sure if there was a late design change or something not shown in the 69 manual?


My 4A Baltimore built 69 Chevelle SS survivor has the exact same vent set up as Rick’s car does. I’ll post a picture if I can resize it. Rick also has the photo if he wants to post it.

I have a January built Baltimore 69 SS Chevelle that only has the tubes as well. It was restored 30 years ago. Has the same bracket as Rick’s.

Here they are. Note that both Phil's and our hoses are too long to even get a vent on. These are the original ribbed hoses and not replacement. The bracket will also not fit the vent at least when I tried with my bracket and a repop vent. I also posted a picture of Grady Birch's car WITH the vent.

mockingbird812 12-06-2018 04:17 PM

Hey Rick. Is there any cover or remnants of a cover or shield of some sort at the open ends of the vent hoses to prevent contaminants from entering the fuel tank?

SS427 12-06-2018 04:31 PM

1 Attachment(s)
This is what I found inside my hoses when I was cleaning them. It was in both hoses but I was not expecting it so when I blew out the small hose it instantly atomized it. lol

mockingbird812 12-06-2018 04:55 PM

Ah yes you showed that before and it didn't register with me. But, it looks like the General considered contaminants getting into the tank. Will you put cotton or other barrier in there to take care of this (you know, for all of those puddles you and Annie will be taking your Chevelle through) ;>) ?

Woj 12-06-2018 05:25 PM

These tubes travel right up to where the structure metal goes horizontal and that would provide some protection from debris. I’d also say this isn’t in a high splash area either and there wouldn’t be much of a water/contamination issue. For that matter, the plastic vent only had foam in it too, at the junction port, and would have been just as susceptible to contaminants. JMHO.

See post #53. ;)

JoeC 12-10-2018 12:47 PM

Rick,
did you get any original tires with it?
what are you going to use for tires?
that is the most difficult part to find for a Yenko Chevelle

SS427 12-10-2018 01:22 PM

I will fill in that part of the story shortly.

ssl78 12-12-2018 03:46 PM

I have theee I believe one was a 69 Chevelle but do not remember what trans it had

tom406 12-12-2018 06:00 PM

That 979xxx tag is from a Pontiac transmission, a '68 GTO spec M20 I think.

ssl78 12-12-2018 07:29 PM

The other one was from a 69 Chevelle just do not remember if it was from m20 or m21

The original cold rolled weld was also visible though I had to replicate it as it mostly disappeared during the cleanup process. I then restored the slip yoke and installed new u-joints, mounted it and covered it in Boe-Shield (which is still wet in the photos). I also replicated the "XF" that would be found on the 69 M21. Still missing is the steel part number tag for the trans though I have a lead on one.

The build sheet calls for a Yellow and Green stripe. When stripping the shaft it looked to be an aqua green and almost like two different shades of yellow but I painted mine the same shade.


Rick, did you use the Boe Shield T9 in the aerosol can?

SS427 12-12-2018 10:04 PM

I use both aerosol and liquid form as well as several other types of sealer.

jer 12-12-2018 11:01 PM

Rick, I notice a bunch of small items that differ from my research. Maybe plant, maybe early/late, maybe the COPO vs. L78, but they're there. I'd like to get together and discuss them if you get a chance.

SS427 12-12-2018 11:10 PM

Please do. I will admit that I am somewhat new to the 69 and they do differ than the 70 so I am more than happy to learn. I will say in my defense that I am ONLY replicating what I found on this car originally and I photo documented everything I found before we ever started but would love to talk.

jer 12-13-2018 01:38 AM

Just to be clear, I'm in no way saying you're not entirely accurate with your '69. I do know that the more '69s I study, the more differences I realize. Heck, my brother is restoring a '69 KC SS that is 3 weeks apart from mine and it has unveiled many assembly line differences on generic parts, not just the option differences. Just trying to broaden my own knowledge.
Again, thanx for taking us along!

SS427 12-13-2018 03:13 AM

Jer, in no way did I think you were implying that and quite the contrary. In the very beginning of this thread I asked for constructive criticism or corrections/suggestions as I do not know the 69 Chevelles like I do the 70 and welcome as much input as I can get. I have gotten a ton offline from members and it has been great! I have always made a point to study every car I restore to insure it is correct especially when I do not know them such as the 68 Yenko Camaro and the 70 Z28 I restored several years ago. Now we are doing another 70 RS/Z28 made within 800 units of the last one so that research is really paying off. Thanks for any help you can supply Jer.

70 Forest Green Zee 12-13-2018 04:26 PM

Rick...having been a big fan of cars that you have restored for many years now I know that when you finish this Chevelle it will be absolutely spectacular! Is you goal still to have the car finished and unveiled at MCACN in 2019?

On a side note....I would love to see pictures of the 70 Z28 that you say you are restoring now when it is finished. You can send me pics directly, pm me for my email address.

mockingbird812 12-13-2018 04:48 PM

Here is the trans tag from my 06A Baltimore M21 for my SS.....

Yes, it will be at next years MCACN. Thank you for the compliments. Here is a before shot of the Z. Sweet car for sure and another M22, 4.10 car.

I did not want to say anything until I had them in my possession but I procured a set of 5 original dated Goodyear Wide Tread GT F70x15's along with 5 1/10/69 dated YH wheels over the weekend after a long road trip. The tires are in amazingly great shape with very low miles on them and most of the wheels are in original paint and in very good condition. They were NOT cheap by anyone's estimate but I want this car to be the best it can be.

Here is a photos of Chad's (then owned) survivor Yenko Chevelle M21, KQ coded rear and his shaft had these colors. They appeared to be yellow/aqua/yellow or orange. Using this as a guide as well as several other people who provided original survivor photos we painted out shaft.

mockingbird812 12-17-2018 03:34 PM

Nice score and congrats with the tires/wheels. Gonna be a stupendous example of a YENKO!!!

However, this is a photos of Chad's (then owned) survivor Yenko Chevelle M21, KQ coded rear and his shaft had these colors. They appeared to be yellow/aqua/yellow or orange so that is what I went by. If anyone else can provide visual proof of what they should be it would be much appreciated.


Sure its not white, aqua and orange? The colors on the green L78 Camaro were white, green and orange.

I know this is Camaro info but "might" be of some use.. Maybe not.

Excellent work btw. Look forward to seeing more of it. :biggthumpup:

SS427 12-17-2018 05:17 PM

Thanks for the help Darrell but no, the Camaro is definitely different and just a coincidence. I have now received a few photos of survivor shafts and it indeed appears that it was yellow, green, orange so time to fix it.

Ryan1969Chevelle 12-17-2018 08:40 PM

I am so happy you found this 1969 COPO Yenko Chevelle!!

I am confident that this whole process is 85% more fun just based on the car being a 1969 vs 1970 :-)

Some guys like 1970’s.... but for me...... you hit the jackpot of all jackpots!!!

Rick, I was lost on shaft color codes and then stumbled on a couple sites that spelled out blue/yellow for an L78 shaft with manual (69). Does the COPO use a different u-joint?

SS427 12-17-2018 11:23 PM

No, there is nothing unique to the driveshaft or U-joints for a COPO.

I have seen the prop shaft color in box 19 listed on at least 10 or so 69 BAL build sheets as BY, for. L78 and L72, also believe Same shaft was used for all BBC with manual trans. There was nothing different on COPO Cars.
Still trying to confirm for sure, but believe BY is black yellow ?
Color codes were not consistent among Chevelle plants.
If anyone has a 69 BAL BS from ANY car like SBC, that lists a color in box 19, I would like to see if any used BU for blue ? Kind of guessing here.
Thanks for any input for BAL built cars.

Mike
