Okay, so I think you all are saying...
Ditch the hubcaps and go with the wheels. Except maybe Tim, I'm not quite sure which way he voted, maybe both ways? And I didn't say but should have that I will be buying new tires. The ones on it are "Winston Californians" whatever the hell they are and they're flat on the bottom anyway.
So the next questions are where to buy them and what size? I see a lot of them on eBay and I'm leery of buying something as critical to safety as wheels sight unseen (gee, isn't that the way I bought the whole car?) but the prices seem tempting.
As for size, the tires on it now are P205/75R/14. I haven't checked to see if they are correct since it won't go, but what size works, looks best?
