Finding 15" Rims for Mazda 323 GTX

[David Disney <disney7@icx.net>]

I am in the process of setting up an '88 323 GTX for
autocross. I can get slightly worn 15" Hoosier autox
tires for free, so I would like to find some 15" rims cheap.

Does anyone know of any rims (that I might find in a
junkyard) that would fit? The bolt pattern is 4 on 4.25
and fwd or rwd offsets seem to work (at least on the
14" rims I tried).

Thanks
