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;
<span style="font-style: italic">(<span style="text-decoration: underline">not</span> tube stampings)</span>

4:56 = 9511-<span style="font-weight: bold"><span style="text-decoration: underline">DT</span></span>

4:88 = 9511-<span style="font-weight: bold">'__'</span>
<span style="font-style: italic">* If someone has this 4:88 order code, please post it here</span>

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!.
