[skidmarks]

I thought they were dana 40 rears in 48 to 52?

They don't have alot of value and would be cheaper to swap in a complete used rear. Street rodders usually junk them for 9"

Or do like stated above. I have used 9 " rears out of 1966 and older. I think the direct bolt in is from a 57 to 60.

Same brakes and wheels
