Spindle Replacement
those are correct for 73~76 A body.
if you *just* need spindles, and you don't wanna mess around with used stuff dr. diff can tighten you up at a very reasonable price.
by the looks of it, you're obviously going to need some rotors if the bearings got that bad. and it appears that the lower ball joint bolt holes are all waller'd out, so i'd inspect your hardware there and replace if it's suspect in any way, shape or form.
so... what happened? we all love a good story!
