Rims with good amount of backspace?

most rims come in many types of backspacing, so decide what wheel you think looks good, then we'll help you with backspacing. It looks from that picture like you have a 65/66, keep in mind that the car itself is the limiting factor in tire size for that year, not the size of the wheel. The most you can reliably go without rubbing is 215 in the front, and 235 in the rear (maaaaaaybe 245, but even 235 is pushing according to fitment charts).

As for choices, I'd go to Summitracing.com and look at their selection/order a catalog. Its impossible to tell a person what type of wheel he is going to like.
