1966 Stang 5 lug wheels

[bmxmon]

You can probably just go to the junkyard and ask for some wheels for your car. Measure the backspacing and make sure they are the same (you can probably look up the stock backspacing pretty quick with google) I've had to do this before when I was swapping over to 5lug and didnt want to spend much money on temp wheels. Ford and mopar had the same bolt pattern. If your just using the wheels to roll your car around the garage, you can probably even get a jeep spare, as I guess they fit perfectly. (and probably even cheaper)
