Remember these cars came with 13" wheels, and tiny tires. At least my '69 Valiant 100 did with a slant 6. Now it has a '76 spool mount V8 k frame, small bolt disc, and 8 3/4" from a 70 dart 4 door. It rides on 15x7" small bolt rallyes, and BFG 225 60 tires. My car sits low with 40 year old leaf springs, and what ii think are .94 torsion bars. It's parked 20 miles away, but I'll check the bumper height when I get over there.
