1970 Duster base model slant 6 rear differential 2070051 spider kit

Thank you sir. If you get to it measure the drum to drum for total width. The 43" ctr to ctr for the springs is correct to my needs.. I'm sure thinking about it. You'll have TO HAVE AN OLD WIRE BRUSH TO SEE THE CASTING #. Should be on the lower right center casting not on the axle housing. Thanks again.
I'll look.
