COPO 9511 - Page 4

**PeteLeathersac** · #31 07-28-2011, 10:52 PM

Thanks for your input and great info!.
Yes the A/F/X-body codes you're referring to were different depending on which ratio 9511 was ordered..

1969 F-body 9511 order codes;
(not tube stampings)

4:56 = 9511-DT

4:88 = 9511-'__'
* If someone has this 4:88 order code, please post it here

Good info on the two known 9560/9561 window stickers w/ the 9511-DT..
Also being originally supplied w/ the BE tube stampings!.

Are you absolute and how so on different gears only being supplied unless first a 9560/9561 F-body or 9562 A-body cars?.

Love to see paperwork etc of known 9511 '69 F-body cars if anyone can share?.
Or any Copo 9511 info, especially for 1969!.

9511CB = 4.88 (3862528-3862516)

I have the "DT" suffix listed for the 3916230-3916231 COPO HD 4.56 and a different suffix for the standard 3862527-3862515 4.56.

Purrrfect and thanks for the '69 9511-CB 4:88 order code!.
Aside from availability questions, is there any indication X-body cars would be any different than an F-body?.

Can you please share any of the non HD codes too?.
And for certain are the non HD 4:56 ring/pinion #'s posted what was factory installed w/ a '69 non 9560/9561/9562 A/F or X-body Copo 9511 order?.
Also are these the same/different than part #'s ordered for counter parts and/or installation at the dealer level?.

Thanks and please post anything Copo 9511, Vette's too!.
No '69 Copo 9511 X-cars yet but we're certainly learning something!.

It seems like you are looking for cars that were built with some unique rear gears…

Here’s a 02A Fremont built 69 Chevelle that came from the factory with 4.88 posi. A friend of mine swapped out the entire rear diff with a more drivable ratio for the previous owner (he sold it at a swap meet some 20 years ago) so unfortunately I can’t get any codes off of it.

This car was the terror of my neighborhood back in the early 70’s when I was a teenager. It ran the typical Cragar SS’s with TA’s – which got smoked on a daily basis. Smoke occasionally came out of the cabin as well, but that’s a different story….. It always had a 454 in it and sported SS454 badges on the fenders from way back then. Bench seat, T400 on the column, gauge package and not much else.

Without an original rear housing to view, and no window sticker or build sheet (at least not yet, the interior is still all original and intact), I don’t think I have anything important to offer at this point in time???

My question is – are there any details that may be left on the car that would help this info gathering exercise? I don’t think the different ratios would require anything else special on the car, but if there is please let me know and I’ll look for it.

Hello,

I have hit bottom with most of my paperwork and manuals. I am still searching the pictures in my files. However my laptop died and will have to wait until I am back from the Nova Nationals.

Great postings everyone and please keep adding anything useful also keep your eyes peeled for any paper on that '69 Chevelle Hubleyman|.
The more we understand the facts of this whole 1969 Copo 9511 thing the better as more previously unrecognized real Copo performance option cars are exposed!.

Here's another possible below, read the ad and note the KM rear axle tube #'s and POP..
Original L78 block admittedly MIA but may be a deal for a real '69 Copo 9511 Chevelle?!

Quick update, I am still rummaging through papers as well but did come across a hand written note that I had forgotten about in one of my binders of dealer paperwork. Apparently the RPO G80 positraction was mandatory when ordering the steeper gears under 9511. This is why I had placed the price at $42.15 instead of $2.15 in my sites RPO listings. I did note it on the site for future reference.

Small steps.

**PeteLeathersac** · #38 08-02-2011, 05:18 AM

The info posted above including this link noted below all indicate G84 was req'd w/ a '69 Copo 9511 order, not G80?.

When you ordered 4.56 gears in a 1969 COPO Camaro you had to pay something like $40 extra over the standard 4.10 gears, if I remember correctly. Had this something to do with COPO 9511 ? Otherwise the cost for installing 4.56 gears shold be almost the same as installing 4.10´s, I think. [img]<<GRAEMLIN_URL>>/dunno.gif[/img]

From the great info shared above and what we've learned so far, yes a '69 Copo 9560 or 9561 car required Copo 9511 to be supplied w/ a factory 4:56 or 4:88 rear axle..
Same w/ a '69 A-body w/ Copo-9562 ('69 L72 Copo Chevelle)..

From what we've learned, a '69 F-Body Copo 9560/9561 car w/ a Copo-9511 rear axle besides noting 9560/9561 would also have included one of these below codes on their original window stickers;
Copo 9511-DT (4:56)
Copo 9511-CB (4:88)

Also from what we've uncovered, these '69 9560/9561 F-body cars w/ 9511 were shipped w/ a BE (4:10) tube stamping but containing factory installed;
3916230/3916231 ring/pinion components (4:56)
3862528/3862516 ring/pinion components (4:88)

Unconfirmed but probable is any 1969 Copo-9562 A-body cars ('69 L72 Copo Chevelles) w/ Copo-9511 would've been shipped w/ their KQ (4:10) tube stamping but containing the same factory installed components as the '69 9560/9561 F-cars w/ 9511 would;
3916230/3916231 ring/pinion components (4:56)
3862528/3862516 ring/pinion components (4:88)

* Again any 1969 Copo-9560/9561 F-body or Copo-9562 A-body cars without the Copo-9737 pkg but with Copo-9511 factory installed 4:56 or 4:88 rear axle would be a 'Double Copo'!.

--------------

Different story for any other 1969 non Copo-9560/9561/9562 cars shipped w/ Copo-9511 rear axle as they'd get window stickers w/ yet to be learned Copo-9511-'__' suffix #'s..
Being Copo-9511 was available for 1969 A-F-X-Body cars & Vettes, also unknown is if these code suffixes appearing on window stickers etc were the same or different than those of an F-body or each other?.

Although order code suffixes unknown, factory 1969 Copo-9511 cars should have the below tube stampings and components (again these are '69 F-body w/ Copo-9511 but non Copo-9560/9561 or '69 A-body w/ Copo-9562 cars)..

1969 F/X Body w/ Copo-9511 - non Copo-9560/9561 cars;
Tube stamping = BW (4:56)
3862527/3862515 ring/pinion components
Tube stamping = BX (4:88)
3862528/3862516 ring/pinion components

1969 A-Body w/ Copo-9511 - non Copo-9562 cars;
Tube stamping = KM (4:56)
3862527/3862515 ring/pinion components
Tube stamping = KO (4:88)
3862528/3862516 ring/pinion components

Anyone please feel free to add missing/more info or point out mistakes needing correction..
Same w/ anything on the '69 Vettes w/ Copo-9511, please add any info known also anything on '69 B-Bodies if available w/ Copo-9511?.

This whole 1969 Copo-9511 thing has been a great fact-finding exercise but besides confirming the above, most exciting and yet to come is finding and confirming any real 1969 Copo-9511 cars!!!
