[$700Spider]

Thanks for the reply. Currently the car has cheap 195/70's on it. Quite a bit of sidewall flex there. I'm tempted to keep the 14's, or I may have the stock Spider wheels made into 15's. Stockton Wheel says "No problem". My other thought is Mustang GT wheels- they fit perfectly! I think the stiffener will be first, though. I just can't stand seeing the windshield shaking like that, although my dad says his '71 was worse before he had a rollbar installed (mine already has one). Oh well, lots of time to figure it out. Fortunately the car runs great already!
