19.5" wheels from some types of Class A motorhomes will have the right bolt circle, but the tires that fit them are the same height as an 18" tube type tire. They will look way too small in the wheel wells of a truck that once ran 20" tube type tires. Like Ed says, those 10 hole 22.5" tubeless wheels that are the proper replacement for a 20" tube type are extremely scarce.

Thanks. Sadly I think you are right.
Custom rims is an option and I could have 1-piece rims made to look exactly like the original rims but right now the cost is 3-4k per rim.
Hopefully as this build develops the cost drops. I can't see any other rim on this car.
