well I've got 1994 gt convertible and it came with 2.73's whether or not that was commen>?< i dunno? But I just ordered my 3.73's and i was wondering where i order possi traction? or is that the same thing as a limited slip differential?

How do you like the 3.73's? I'm thinking of getting some for my 94 GT. But as far as the limited slip, I think they are the same thing.

Posi traction is just GM's name for a limited slip diff.
