255-60's will fit on 15x7's on a 70 Swinger

Damn that car looks so good! Ever time I see it I looked better and better lol. I really like the color combo!
Off the topic but did you push the bumper back and delete the "skirt spacer" thing?

Thank you.
The 73's don't have the skirt, but I did push the bumper back about 1 inch.
