How would i make this work for me? 83/4

That Dana looks like it came out of a truck. You'd probably have to have 6 or 8 bolt wheels to use with the brakes that are on it. You can probably find a set of 10" or 11" brakes to fit an 8 3/4" rear either here on FABO or in a salvage yard somewhere. I think you can use brakes off of a C body too. If you were closer I've got a set of 11" brakes you could have cheap but the shipping would be a killer. Just be sure you get everything from the backing plates on out, including the E-brake cables, just in case you need them. If you can find a complete B body rear with axles you might be better off because you may be able to have the axles shortened to work with the rear if you need to have the rear narrowed, plus you'd have the brakes already there.
