They were rusted pretty heavy inside. I need to pull them off the car and look again, but the studs were about gone and inner structure really rough. The other thing is to rechrome I need to be able to take the rubber off and have studs intact on them (go Karl, lol) As I recall the nuts inside look like little gobs of rust. So probably junk if taken apart. There is a pair of NOS rubbers on ebay right now for $80. Kaching...$$$$. Unless I can find a 'pristine' used pair, I may use what I have for a while or run without till I have more available $ to get a set chromed.
