Being the instigator of this Copo 9511 mission w/ my postings of the previous thread, I thought I'd better weigh in w/ what I understand..
Any and all Copo 9511 info is great to learn but specifically the situation for 1969 is most interesting, especially w/ respect to X-body Novas!.
Keep in mind that rear axle gear options were available for 1969 production a few different ways including dealer installation, other Copo options that included it w/ their package also the Copo 9511 option we're now discussing..
Being a Copo 9511 rear axle is a true performance Copo option, this is an important fact and waaaay different than an appearance option supplied by a Copo # or other special order method..
* Again I believe the Copo 9511 option for 1969 model production was available for <span style="text-decoration: underline">4:56 or 4:88 only</span> so higher than, <span style="text-decoration: underline">NOT including 4:10</span>..
<span style="text-decoration: underline">Copo 9511 Rear Axle/1969 Chevrolet model year production:</span>
- Copo 9511 was necessary to get <span style="text-decoration: underline">factory installed rear axles
beyond 4:10 </span> in a 1969 model year Chevrolet..
- This applied to A-Body, F&X Body cars also Corvettes too!.
(Different situation in years other than 1969 also unknown what
was req'd w/ other GM brand A-Body cars etc for '69?)
- 1969 A/F/X-Body cars & 'Vettes were built/delivered w/ the Copo
9511 rear axle option..
- Documents for Copo 9511 '69 Camaros shipped exist including a
Z28 also a Copo 9561 L72 car, hopefully more!.
- The Copo 9560 or 9561 Camaro w/ 9511 would be a Double Copo
without having 9737..
- A Copo 9560 or 9561 car w/ 9511 and 9737 could be a 'Triple Copo'..
- Since at least one Z28 Copo 9511 was produced, if any non
9560/9561 cars were built w/ 9511 & 9737 they'd be a
Double Copo too!.
- If Copo 9511 included components other than the rear axle supplied is unknown but questionable considering the option $ amount?. (rad etc)
- Other Copo # 1969 model A and F-body cars also 'Vettes were produced although a '69 Nova w/ Copo 9511 may be the only '69 F-body Copos built but regardless is <span style="text-decoration: underline">a real '69 Copo Nova</span>!!!
----------
An interesting document to review is the below ECL Sheet from CRG..
Note the references to Copo 9511 appears a few times..
Keep 'er going fellas and lets learn all we can!.
