exactly how plain? a lot of companies make plane steel wheels, usually painted black. a lot of them are marketed as 'nascar style' and cost less than 30-40 bucks a pop. cop cars and such are another possibility, you could go to the junkyard and start checking bolt patterns.
Well, my dad needs some plain wheels to put the factory hubcaps back on his 63. Factory rubber was 8.00x 14 which translates to 205/75/14. We need the original style 14 x 6 rims.
