They are whatever you see when you are changing the fluid. (as you clearly need to do)
Most common ones to find in that application would be 3.23. But no guarantees after almost 25 yrs.

According to the 91 database
https://www.thirdgen.org/1991-chevy-camaro/
There is only one option for a 91 Z28 with an A4 and L98 350 TPI.
Your car originally came with 3.23 gears but that doesn't mean they're still original. Change the oil and count the teeth.
