Magnum 500s

Man I do not know. I vaguely remember them being 14 x 7 or 6.5. I am pretty sure they were 14. I am sure you would want to run 15 or bigger.

Also, here is an interesting repro but has deep backspace 5.9" and requires machining the center register out slightly to the proper diameter to fit front mopar hub (maybe rear hub register too). A bit of research required to make these work. Upside is 18 inch by 9 aluminum and the price. 144$ each.

Yea I would want to run at least 15x8 which is the size wheel I have on the back now, front i am thinking either 14x6 or 15x6, I have 14x6 on there now. Those wheels are interesting and give me more to think about. I can see why some research would be required to make those work, thanks for the link.
