1968 GTO rear end question
Hey guys, I know this subject matter, rear ends, has probably been beat to death. But as we all know, 12 bolt rear ends are getting pricey out there. Anyways, I have a chance to get a 12-bolt rear end housing (without differential, gears and brakes) for a decent price.
My question is there is a difference in Pontiac rear ends versus other GM A-Bodies? I thought I heard that Pontiac, Olds, and Buick have a different rear end than Chevrolet, is that correct?
The "numbers are 40992 cant read very good 255 has R2 had 2.56 gears has C10 measures Flange to flange 55 3/8 long..All mounts look same as 70 Chevelle,, has Carrier Main Caps and bolts.I think these came in 68,69 Skylark,olds 442,Cutlass". Sorry, I am quoting seller here.
Is this a rear end just for Olds and/or Buick or can it be used on a Pontiac?
