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 - <span style="text-decoration: underline">non</span> 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 - <span style="text-decoration: underline">non</span> 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!!!
