Basics of engine are stated above, just had the tranny rebuilt with the TransGo street shift upgrade installed. Now I'm looking at the differential, I know it has 2.73 gears but don't know if it's a 8.2" or 8.5", any guesses? I've looked for coding stamps on right rest axel but can't see any.
I want to upgrade to 3.73 and possibly a posi. I was thinking about searching a couple salvage yards around here but have no idea what years/models would be compatible. Any ideas on how I can figure this out?
