I've got a pair of original wheels for my '99 Miata that I'm giving away to anybody who'd like to come take them off my hands. The other two were severely bent, but last time I had these checked they were straight. No visible curb rash although they are dirty as hell at the moment. But also free.
Send me a PM, I can be at home most times during the week to hand them off to you. Bring me a beer if you want to be cool.
