wheel fitment on 65 valiant

Be careful of 4 1/2 '' backspace on the front. On 3 cars,a Duster, Belvedere, and a 63 Valiant the wheel lip comes very close to the upper a-arm upper ball joint and hits any wheel weight on the inner lip of the rim. Both Aluminum and steel. I had to use stick on weights or trim a little from the a-arm lip.Factory mopar steelies are 15x7 with a 4 1/4'' backspace and work just fine.I ran that size on the 63 Valiant.Just a thought
