An accurate 8 3/4" rear axle width list

i just ahve a quick question, can a 8 3/4 from a 66 dodge charger be made to fit my 1969 dodge dart? i know the springs need to be relocated but im cool with that but will i need to have the housings cut?

You don’t necessarily NEED to cut the housing. That rear axle will add a little less than 7/8 to each side for backspace compared to an A-body 8 3/4 with BBP axles. So, for example, a 15x7 with 4.25” of backspace isn’t s bad choice for a BBP a body 8 3/4, but to keep the wheel in the same place with the 66 B body a 15x7 would need 5 1/8” of backspace. That’s doable, but it would probably be a custom rim in a 15” diameter. In a 17” rim it’d be a piece of cake.

Just depends on what you’re doing.
