Um...

The ring gear is 7.5", and the gear ratio is 3.08:1 :hick:

What other specs do you need?

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

That's the logic :shakehead  at FoMoCo, but I guess it makes for a good reason to swap in an 8.8 rear.

why do they do  like that


1.)  It's cheaper to produce and assemble than a Trak-Lok

2.)  The average buyer of these cars when they were new probably did not care (especially if they purchased a V6.)
