15" x 15" Aluminum wheels, 5" bolt pattern

polished super tricks work?......got a set coming off the Butch Leal / California Flash B/MP Hemi Duster I am gonna peddle.

I need more like 15" x 12" (wide) for period correct (14 x 32) slicks.

they are dual bolt pattern....the smaller pattern is 4-3/4"....I think the larger is 5"
I have some Super Tricks, but not that wide. I like the modularity of those wheels in that you can just unbolt them and change an offset or width easily. I like the period correct myself, but a modern 14" x 32" stays flat on a wider rim without wearing the center of the tire out like they do on a 12" or even 14" rim.
Thanks Tom
