well i got some questions for you guys today the first is what size rear end usually came in the v6 firebird's, and if i were to swap a bigger rear end in whats the simple way to do that in the bird without dropping the whole rear end and cursing, and another question should i go with 3.73's or 4.10's?

 

7.5/7.62 10 bolt. easiest way to change gear sets is to drop the rear, ratio will depend on your application
