There is a caliper rebuild shop near me that claims to have the correct piston for the 88 rears. I am under the impression that this is a part that has been discontinued a long time ago
He sent me a picture and measurements. Can someone please confirm if this is, in fact, the correct piston for 88 rears?
Dimensions are apparently 1.871" in diameter & 1.985" in length.
thanks

Can't find info online about the difference between the 84-87 rear piston vs 88 rear piston.

That part is not the problem - it is the inner piston and seal that fits inside these. I bought outer pistons from Rockauto about a year ago when I had mine done.
The seal for the inner piston can be used from the f-body kit (CENTRIC 14362008). I believe there is a difference in the piston size when comparing to the previous years.
You need the seal circled in red from the f-body kit:
