again..the B-body 8 3/4 will fit with moving the perches

but the rims will need to have some more back set to fit in the wheel wells and not rub the fenders lips

so ya gonna need some rims to go with it

I had one cut down to A-body specs and used the moser axles with green bearings

that made the whole rear a 1/2 wider..1/4 each side and used 4 1/2" backset on 7" rims in a 68 Dart

you will need to have more than 4 1/2" so measure carfuly
