Wondering if anyone can help me?
I've got a 70 Lemans Sport clone with 350 3spd auto, the rearend I was told is 2:78 10 bolt 8.25 open rearend.I'm wondering what donor car can I get 3:73 or 3:55 or should I rebuild this rearend? Any suggestions would be great thanks |

You can use any 64-72 GM A-body(Chevelle,Skylark,Cutlass,orTempest)rear.The 64 had a bolt on rear spring and along with the 65&66 they were 1/2"/side narrower than the 67-72 rears.Chevy rears use a smaller ujoint so you would need a double sided ujoint to use a Chevy rear.Any 69-72 G body rear(Grand Prix or Mone Carlo)will fit also.Just have to look til you find the ratio you want.

If you want the bigger gears and are doing a motor to match, definitely replace the rear. The cost to upgrade yours will get quite expensive and it will never have the strength of a legit 3:36 and bigger rear. If you just want a highway cruiser, just drop in a posi unit. They are more readily available for your gears.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
