mdkelley -- I faced a similar situation about 10 years ago with my '65 GMC 4000 series truck, only all 6 of mine were RH-5s with the 6-lug pattern. With some patience, a tape measure and a LOT of walking through junk yards (plus some help from Grigg and the ODSS gang) I was able to come up with 7 single piece tubeless wheels. Look for trucks like the one in Ed's picture, older Ford U-Haul trucks and school buses/airport shuttle buses.
