Leaky axle shafts

Axle seal replacement is about as easy as it gets but I question the effort of doing it on a 7-1/4 (can we say super light duty) rearend with a car that's running a v8 and a 4 spd. If it were mine I'd look for an 8-1/4" rearend. You can buy them pretty cheap and they'll take a lot of abuse. Not as much as an 8-3/4 but you don't need an 8-3/4 with your little 273 and an 8-1/4 will cost less than half of what an 8-3/4 sells for.
