Since then, sets have been non-existent...Murphy's Law??? I think Gerry may have gotten the last set...but brain is not real clear on that...
The extra wheel that I found actually was reunited with it's original car!! I had old pictures from the car passing through different hands, and the wheels had a distinctive paint scheme, AND I knew the geographic area from which both came!
That's not gonna happen very often!
Just gotta keep looking....or campaign for a set in 16 & 17 sizes???

I'd spring for some larger diameter rears....if you can still get the larger circumference rubber....to fill out the wheel wells. The small tire thing on the rear makes me think roller skate.....not to mention buggering up bellhousings and oil pans.....! ouch...
Ciao!
