70 Chevelle SS Questions

[3macs1]

These questions will be easy for you guys and I appreciate the help. I refound a 70SS Ls-5 conv ( i think) today that was reported back in probally 79 to be smashed beyond repair. The guy that has it lets just say I have to be very gentle with flew off the handle when I asked him if it was ever smashed. No pictures allowed, etc.But interested in selling ( i think) I knew he had a mint
72 malibu conv that has now vanished and suspect she is now the 70. All the typical 70ss gear that I know to look for is in place but I would like some help on the following about 70 SS chevelles.
-did all 70 chevelles have the two piece brake rotors
-did they all have the plastic inner fenders
-was 70 the only year for the flat bottom windsheild washer container and the fluid level monitor option.
-did all chevelle big block cars have the adjustable lower steering shaft coupler
-was there a quicker ratio PS box on the 70 SS.
-were the dash vent louvers smooth black not textured only in 70.
-was there two different master cylinders 309 dual clip and single clip
-did only big blocks have the oval lower control arm bushings
-original exhaust tips welded on with no part numbers
-fan shroud same as 69 BB
-back up lights section in tail lights raised not flat like replacements.
-location of white plastic hood pin cables
-reinforcement welded to upper left training arm.
- Dual fuel lines
Any other items I should look for??

I can answer most of these Joseph and others will also chime in on the rest.
-did all 70 chevelles have the two piece brake rotors
No, only the early cars had the two piece
-did they all have the plastic inner fenders
No, some had both, some had both steel and some had one of each.
-was 70 the only year for the flat bottom windsheild washer container and the fluid level monitor option.
I can only answer for 1970 and they were the flat bottom. The later verson with the same part number had the angled bottom.
-did all chevelle big block cars have the adjustable lower steering shaft coupler
Yes
-were the dash vent louvers smooth black not textured only in 70.
Yes
-was there two different master cylinders 309 dual clip and single clip
Only the single bail "409" cylinder was used on the disc brake cars.
-did only big blocks have the oval lower control arm bushings
The SS Chevelles used only the round bushing.
-original exhaust tips welded on with no part numbers
Yes
-back up lights section in tail lights raised not flat like replacements.
Only on early cars.
-location of white plastic hood pin cables
Varies by plant
-reinforcement welded to upper left training arm.
On all 12 bolts as far as I know.
- Dual fuel lines
Only on late cars.

Thanks Rick for the response it is a big help. Is there anything else I can look for to make sure this car is a 70 and not the 72 shell. Did chevelles have a hidden vin number like some other gm's. She has oval bushings,a 309 master cylinder, one piece rotors and single fuel line.It's getting interesting.

Now thats GOOD information!

Somebody needs to put this stuff in print!

Sure would help build a better clone

My apologies Howard since that is not the intention of my post.These questions were to ensure I donot purchase a rebodied car for the price of an original.I believe this was the correct form to ask my questions and appreciate Rick taking the time to respond and help me out.
This knowledge is of no value unless you have the understanding, components and ability to put them into place.
One thing I have learned in the 30 years I have owned and been around 70 chevelles is the more I have learned from working on them the greater the doubt and the more I look at when purchasing one.

You're kidding, right?

One other give-away on a 70 to 71-72 rebody....
71-72 gas tank "vent" system protrudes into the trunk floor behind the back seat.
70 did not have this vent system, a 70 upper trunk floor section is flat.

Thank you gentlemen. Went back today and the trunk pan is a dead give away. I never owned a 71 or 72 just 70's so I learned something new to look for in the future. She is not a 70 body that is confirmed since we didnot have that cannister option in 70 up here. I am interested now to look at the trunk of the next 70 calif car I see to determine if they have the 71/72 style pan or not.
I have to say he did one hell of a job putting her back together considering when we looked at it years ago the back bumper was pushed within inches of the front buckets. Still some pretty with the ls-5, no.28 fathom blue body, white conv top and white interior. I am a sucker for that combination but not a $75,000 sucker for a rebodied car with her history. Yep. All matching numbers, build sheet and GM documentation. He does not own a computer or is a club member just a 70 assembly manual I seen on the bench helped him through. I told him openly before leaving what I thought of the car, why I was not making an offer and hopefully that he will be honest with the future buyer on the car's true history. Also told him why his cowl hood would not stay open but I will leave it at that.

Sorry my post was misunderstood by you. I didn't mean anything by them other than I wish both of the Rick's could put some of their knowledge in print. But then someone would use it to build a better clone. I know your intentions were pure. Just another example of how words when printed without facial expressions, inflection, and body language are easily misread.

No problem Howard thanks for taking the time to clarify.
On the clone issue I think they have a place since you can customize them and drive them without worrying about harming the value of a genuine SS.
The problem comes when they are sold for top dollars to unsuspecting buyers as originals. In my mind the reproduction of cowl tags, build sheets, etc. has to be stopped as a starting point, with heavy fines associated with vin removal or reuse.In Canada we have the ability to get the GM documentation which helps but would not in my situation with the conv.What I am seeing in the last few years is chevelles seem to be falling out of the sky. For example in my small town we had one 70 ls-6 purchased. I knew the owner, drove the car and know exactly where it sits today. However now there are three being put together within 50 miles of me all were basket cases pulled over from the US side and of course matching ls-6. BS.
Some friends with original ss cars here are purchasing repo trim rings, hood pin cables, mirrors,ww mouldings etc. for driving and switching them back and forth for shows.
That is where we are which is sad but real and it will probally get worse once they repo the chevelle body which is not far off.
