8 3/4 vs Dana 60

Its is really only a question of how you want to spend your money. Either one will work fine. They both have certain pros and cons in this application. Unless it is a single-purpose-built car, there is ALWAYS going to be some compromise, no matter what you use or how much you spend.

You already have the Dana, so why not just use that? Unless I missed something and the car already has a 8 3/4 under it?
