Rear axle bearing 62 valiant
I was just looking at rock auto--- I do not think they are correct-- the rear axle bearing is not a taper bearing -- it is a sealed unit--- one of the bearings they showed also said it fit a superduty f350??
Ebay, Andy Bernbaum, some other old time supplier might have them..
Best bet is to put a 63(later style) & up rear in it-- most people will give away those 7.25 rears.
Good Luck, Lawrence
