if your talking about putting an axel under something like a 66 dart or a 64-75 B body mopar many people used the A100 axel and springs, they have to be narrowed to fit under a dart.

or are you talking about an older car like a streetrod?
I would go with one from speedway if you are doing a older car or truck. Ron....
