Im in the process of installing a LS3 engine into my 1977 Trans Am .. what all would i need to remove from the trans am??? and what do i need to buy in order to make it fit....would i need a stronger axle?? suggestions are appreciated.........dont wanna spend the six figures for the YearOne Bandit, Prefer to do it myself
Your car should have the factory posi unit already, run that. Stock axles are stronger than you would think. Add c-clip eliminators if anything but, if this isn't a race car and running 10's, I wouldn't worry about any of it other than having the posi.(or as GM called it "limited-slip diffriential") The "Corporate 10 bolt" that was put in our 2nd Gen's didn't get any love because the 1st, 3rd and 4th Gen 10 bolts are weak, hence the stigma. They're pretty stout, especially with aftermarket parts. Keep us posted.
