they should fit, but it's impossible to say because they will be real close, the rear should be a 10" rim with a 5.5bs a 5.75bs or a 9" rim with a 5.5bs would be even better but you'd get a bubble effect on that wide tire being it's so short. i have 29x12.5 mickey's on my 70 but had to roll the lip and also added stoppers to keep the fender from coming down too far, they just barely touch the bubble of the sidewall.

i don't know the bs is what makes the determination. i'd just put them on and see if they work. cheap enough just don't balance them until you see if they will work

They should work OK, but backspace is key. You'll need just a little more than half of the rim width as backspace. I run a 8.5" rim with 5" backspace and it's real close to the tail pipe on the inside. Centerline makes a rim that is 9" wide and has 4 3/4" backspace which would be about perfect on an unmodified 70-72 body. Lots of guys run 10" rims with 5 1/2" backspace but you might have to roll the inner lip of the quarterpanel and re-route the tail pipe (if you have a stock routed exhaust system).
