8 3/4 Rearend Question

yeah they can be modified but i agree with fishy 68 let someone with a jig do it for you but if you can get it for a good price and it has 3.55s and a sure grip you should jump on it keep in mind the center section alone is worth450.00+ so if you got a good price lined up you could even just use that but if you plan on mini tubbing etc you could just have the truck one cut down and go from there. I think also you will need the axles like fishy said and i think you also need different brakes to fit the a body bolt pattern. Good Luck Justin
