I have an opportunity to pick up a "B" body 8 3/4 rearend housing which already has the spring perches relocated to 43", but the flange to flange width is 55". The 7 1/4" rearend under the car now is 53.2" flange to flange. Will there be any problems with an extra 0.9" on each side of the car as far as clearance for the wheels?

If not, what size tires will fit?

dusters are blessed with big wheel wells (comparitvely). you might need a little more offset. i used a set of mitsubishi FWD wheels on my 1972 Dart a few years back when i did the same swap. i worked with the factory 14" wheels, but not well. (some rubbing in corners and such, probably could have fixed it by rolling up the fender lip)

I have a b body 8 3/4 under my race car and run10 inch slicks on 10 inch wheels it works good. But i use stuff that most racers say will not work. It worked damn good at Wilksboro this past weekend. Thanks Ron Parker

Ron,

Is your race car a Duster? What size backspacing on the 10 rims?

Ok that was no a very good answer so i went and measred and it look like 5 inches of back space Thanks Ron Parker

OK. I picked up the rear axle assembly yesterday. The thing has 11" brakes on it. Is that good? Seems large. Does that mean 15" wheels?

I also picked up a 741 3.55 SG. I know, I know, it isn't the choice piece, but is anyone else using one?

The 741 is a good unit nothing wrong with it will do just fine.Thanks Ron Parker

Late model Mustang rims will fit as they have more backspace and are plentiful. I have Mustang 17x8s and 16x8s on my Darts/Valiant.
