Hi Guys, I'm looking to swap out the differential in my 1962 Buick Skylark with a later model heavy duty unit that will handle 300hp. It would be great if something would just bolt in but I'll do what is necessary. I'd just like to start with the right piece. Posi and disc brakes would be great but not necessary at this point. I also need to know the length of the stock differential if anyone knows it off hand? Thanks for the help, Bob.
