On my old 74 Duster I ran 15x7 front, 4.25 BS, 235/60s.
Rear, 15x8, 4.5 BS with 275/60s.
Pretty stock height, nose down just a little.
Had to trim bottom front corner of ft wheel openings on a diagonal, about an inch for plenty of clearance.
Had to put a 1/4" spacer in @ ft spring bracket to move the rear axle back.
There's a fair amount of variance on those cars, even side to side in back.
