Steel wheels...15 x 8, 4.5 BP, 5" to 5.5" BS...

I know it's a long shot, but...

I'm looking for a pair of 15 x 8 OE type steel wheels with a 5 on 4.5 bolt pattern. Need back space of anywhere from 5" to 5.5".

Cash in hand, or...have a pair of BRAND NEW 15 x 7's, 5 on 4 bolt pattern with a 4.5" back space to trade.
