I have a pair of 15x9 with 5x4" with 4 3/4 backspacing. I ran 10.5" wide 28.5" tall Firestone slicks on a 1972 Duster 340 with these. Would these work for you?
I have two(2) Mopar NOS W2 eco heads part number P3870812 and a NOS Holley Strip Dominator Intake part number 4007639 that I now want to sell. Both heads and intake for $2300.00
