Wheel & Tire Combo for '74 Duster

We haven't purchased them yet, but after much research we've decided to use 205-70-14 on 14x6 (4"bs) for the front and 255-60-15 on 15x8 (4.5"bs) for the back of our 73 Duster. We're going with Radial T/A's on the Magnum 500's that Summit sells.
The fronts will tuck in the fenders like stock. The rears will fill the fenderwell nicely. I'm told we may need a 1/4" spacer to clear the springs, but that's not a problem.

Thanks,
Ken
