Question About 15x6 Wheels on Front of 69 Dart

[1969VADart]

I think I have narrowed down my choice of wheels for my car to 15x6 on the front and 15x7 on the rear. Car is a 69 Dart GT with stock suspension (but rebuilt front end and new leaf springs). It seems that 15x7's in the back with 4.5" backspacing seems to be the right way to go on that end. My question is, what would the backspacing likely need to be on 15x6's on the front? Don't know if it matters, but this is with SBP front and rear. Thanks.

4" or so will work.

I have 15X6.5 wheels on the cuda, with 4.25 backspacing. 215/60-15 tires if that helps. Any taller and you will hit the lower fender lip.
