A 55/64 Chevy car rear axle fits pretty well but on 58/64 you have to cut all the brackets off.

The 68/70 something Nova rear ends are the most popular but you have to run reverse offset wheels or the rear tires won't clear the bed sides. That is what I have under my 48 and I had to carry a chrome reverse spare to be able to put a spare on the truck.

I ran a 65/66 12 bolt posi under the 48 for a lot of miles including a trip to Texas and a trip to Ogden Utah and tire clearance is good but again it's a lot of cutting and trimming and those rear ends are getting hard to find.

You need to measure mounting flange to mounting flange where the wheels mount to get it right on these rather than to the back side of the rotors or backing plates.
