8 3/4 axels???

Look for an earlier b body housing, It will measure 59 1/2" from wheel flange to wheel flange(where the wheel bolts on) then move the spring perches in 1/2" on both sides,it will measure 44 inches to center before you move the perches and 43" when you are done. then just get 8" wheel's with 5" backspacing and it will fit right under your car,Redhot just did this swap to his 67 dart gt and I have done it to my duster.I paid 100$ off of e bay for my rear and it was complete with 2:94 new wheel cylinders brake shoes and hardware installed!!!
