Anybody running 276 gears?

That's not quite the right timeline. 2.76 rear gears became standard equipment in 6-cylinder and non-perf V8/automatic A-bodies for 1968. The wide-ratio gearset didn't come out til 1980, when 2.45 and 2.26(!) rear axles were being used in heavy cars with weak engines. 0-60 maybe sometime next month!

Plus 8.75 never can have too many center sections with gear options.
I have 2.76 thru 5.xx gears to choose from depending on what I am building.

It is interesting how the 8 3/4" axle only went as tall as 2.76. One look inside will show how the taller gear, the bigger the pinion gear. The 2.76 pinion is a tight fit in there.
I've thought about the gears that the automakers used in these cars. Lots of GM cars has 2.56 and even 2.41 geared axles. Were there any gears taller than that? I don't know about Fords.
Our 8 1/4" axles had that 2.45 ratio. I thought that the 2.21 was also in the M body Diplomat/Gran Fury and Fifth Avenue cars but wasn't sure if they used 7 1/4" axles, 6 1/4" or both.
