Just something to roll the car around on?

If it's small bolt pattern still pretty much any 14" factory steel wheel should go on no problem as long as the tires aren't super tall or wide.

If the car has been converted to large bolt pattern and your looking at nice wheels to keep on the car a 15x7 with 4-1/4" 4-1/2" of backspace and a 235-60/15 in the rear is a safe fit that shouldn't require rolling the fender lips or anything of that nature.
