Customer Question

I have a 1989 corvette convertible with factory wheels. Car was stored under cover outside for 9 months in Florida
I cannot remove center cap on all of the wheels to access lug nuts. I can and did remove wheel locks using factory tool. I have tried using penetrating oil with no success and have checked with corvette parts suppliers with no success and corvette forums
Any ideas to help me ?
Thank you *****

Is the bolt holding the center cap on the problem? Is it stripped out or just not moving?

I have removed all 4 locking center cap bolts as previously stated using factory tool. None are stripped or cross threaded

But now the cap itself doesn't come off? There shouldn't be anything to hold it, unless the aluminum has oxidized and swollen and is holding it on. I would try hitting it with a rubber mallet to jolt the corrosion loose and they should fall off. If not, the caps are readily available so I wouldn't worry too much about damaging them, better the caps than the wheel.
