I knew the 8 1/4 and shock pates are the same as 8 3/4, I will buy new u-bolts from Napa, I need a pair of shock plats, Thank's for the info but still looking if anyone has a set.
I thought that the 8 1/4" axle took the same plates as the 8 3/4" and Dana, but wasn't sure and didn't want to mislead.
Mancini makes a nice repop for the 8 1/4", 8 3/4",M & Dana that is very nice and looks much stronger than the originals. We used them on the son's 71 Valiant.
