I just went through this.
There are a couple places that can get you a replacement depending on how long you can wait and how much you want to spend.
To repair the wheel it must be stripped of chrome, annealed, straightened, welded, chromed, and heat treated. This might not be the correct order. It isn't a DIY process. As far as I know no place in Wisconsin can do it.
Wheel Collision Center quoted me 6-8 weeks and ~$400 a wheel for the repair because they had no more 94-96 17" chrome Spyder type wheels. They said they had to see the rim to be sure it could even be repaired.
Check all your rims, I found that two rims were crack when only one seriously leaked. It wasn't till I had the rims off that the second one showed. My other two rims had corrosion at the bead so they needed a re-chrome too. Luckily I bought a used set from Jesse.
Two weeks later Rims and wheels called me back to tell me they got one in stock.
You should call each place instead of using their web forms. Calling saves allot of time and aggravation. Good luck in your search.
