71 duster bolt pattern?

[bland15]

I have a 71 duster that had a 340 in it and has front disc brakes and a 8 3/4 in the back. I have measured the bolt pattern and looks to be 5X4". Is this correct? Any ideas on the largest tire 15" I can fit in the rear wheel without moving the springs and what backspacing? Thanks

5 on 4 is correct.....

Any ideas on changing the bolt pattern to 5x4.5????

change over your axles at the rear, and either buy new discs or find some off a 73 and up dart or duster, or a different body style

I have a complete set up from a 74 Duster for $325 + shipping

Easy swap.

Rears - you either have to drill your stock axles/drums or replace the backing plates/drums and axles with a BBP set up.

I also have a set of SBP disc/uppers off a 68 Cuda with good rotors. They came from a running driving car.
