Have you tried Cass? He shows a set for $295, with green bearings.

the 62 housings have the axle nut & need puller to remove them.. All u need to use is a 65 plymouth or dodge 8 3/4 the fit perfect in a duster & the axles are strong. we run 10's all day on stock axles
I'm really old school and not a fan of the green bearings.
I'd like to find a good set of C-body axles and have them cut down, or find a set already done.
