71 dart 17 inch wheels 5x4 bolt pattern

I have a 71 dart drums front and back stock suspension in front. I have 8.75 in back a body stock. I'm looking at American legend wheels in a 17 inch I've looked on here but kinda coming up short on a answer as to what backspace and tire size works best for a stock suspension. The bolt pattern is 5x4 also. If anyone has any pics of theres that would be great thanks.
