15x8 steel wheels, 5x4.5BP, 5 or 5.25BS

Hello everyone,
I'm looking for a set of 15x8 steel wheels for the 9" red circle hubcaps. 5x4.5 bolt pattern and 5 or 5.25 backspacing. Yes, these would have been custom wheels. Since Stockton Wheel is no longer in service, getting a set made does not seem to be very simple. I have called around to various other wheel makers with no luck. TIA.
