Rear end type
Ok, this has probably been asked before, and I can't find it in a search however...
1985 Rear disc Trans Am's that had 5-speeds, were they all 3.73 gears? Apparently someone swapped out the console or did they look like the 83-84 model consoles, I didn't look for a SPID lable in the console.
Would this be worth swapping out for the 9 bolt 3.23 rear that is in the GTA I am putting back together?
I want a lower gear without the noise that I hear the 3.70's for the 9 bolts make and it seems that the 3.45's are almost impossible to find now.
