What other rear ends will work with my Dart?

I put an 8.75 under my last car - then bought axles (Moser) and had them made with 5 on 4.75 pattern (yea, typical Chevy) - mounted Wilwood disc brakes on it too... too bad you are in Cali. - I still have it and would sell it.
What gear ratio? Strap it to a pallet and ship it?
