1972 swinger tire sizes, ansen sprints

245's will fit most of the 70+ swingers with stock spring locations, but whether they'll fit with that backspace depends on the axle width.

Do you have a measurement for the width of that 8.8 from wheel mounting surface to wheel mounting surface? Every car is a little different because of the body tolerances on these cars, but if you can get that measurement I should be able to give you a better guess.
