69 Dart Conv tire check

just as a data point:

68 dart, 8.75 w/ BBP axles, 15X6.5 4.25BS steelies, 235/65 cobras, hotchkiss springs (so it's low), i can just barely fit my fingers between the lip and the tire. the driver's side has a little more room than the passenger.

i think you're going to be very, very close.
