Is my rear end 7.5"?
I've done a search and just want to confirm.
Is my 1987 2.8l t5 Sport Coupe a 7.5" rear end? It has 3.42 gears.
I'm just asking because I found a good deal on a third member with posi and I really wanted to switch but it's for a 8.5"
Thanks

you have a 7.5/7.625 ( you have a 7.625, but gears are the same between the 7.5 and 7.625, but the carrier is a littel different internally).
the 8.5 piece wont work
