Why spend $650 for a bunch of parts that you are going to scrap anyway? Just buy a new 8.75 housing made to the length you want it and forget the resto crowd prices. If you aren't restoring a car then don't pay resto prices for parts you don't really need. Have Doctor Diff build you a new 8.75 rear end if that is what you want. He can supply it with disc brakes already installed and your choice of differential.
