I have a '57 3800 with 4.56 rear gears. I've located a yard with a 3/4 ton 4.10 HO52 rear. I've read some posts about this swap but I'm not well versed on differentials. Can I buy just the ring and pinion or do I need the entire rearend? I'll have to pay shipping so I don't want to get anything that I don't need. Any advice will be appreciated.
