69 valiant 275/60-15

The rear end is a standard a body with actuall bbp axles. The rear brakes will be disc, and im not sure if the tires will fit in a 73 swinger but i dont see why they wouldn't. Just have to measure, measure, and measure some more! The offset kit i got off summit.

I am trying to figure out why your tires are right up against the springs???
I own a '71 duster,stock width A body 8 3/4,big bolt axles,big brakes. I ran a set of 8 inch weld draglites with 4 1/2 inch backspace and 275/60-15 tires. I had at least 1/2 clearance to the leaf springs.
