the recipe that should fit everyones E-bodies
1962 to 1970 B-body (2 or 4 door) 8 3/4 rearend
That is a rearend that has a springseat of 44 inches
center to center and an overall length of 59.2 inches
from brake drum to brake drum
Dana 60's work well too
buy the 2 inch longer offset spring hanger from Mopar
A-body Super Stock springs or equivalent
10 inch wide wheels with an offset of 5 1/2 inside and
4 1/2 outside
295 / 50s size tires on 15 inch wheels
275 / 60s look interesting too but the drivers side fender lip might need a quarter inch or so trim as
the outside of the tire is closer on that side .
