Help Identifying Duster Rear End

gotcha

good looking car

did you get a chance to look at the chart i posted?
it seems to me, you got a 7 1/4 rear end in there, easiest way to tell is count the bolts on the cover
if that's the case I'll probably buy a full rearend to install.. make a roadtrip as Denverr has no old car yards anymore lol!
