7 1/4 to 8 1/4 swap on a '63 ???

Do any of you guys know of a year, make or model that would be as close to straight swap as possible? I don't mind moving spring perches but I don't want to have to rebuild an entire axle to put on my '63.

63-76 Abodies, are all the same width.
73-76 prob big bolt pattern.

no matter what year, driveshaft will need to be modified.
