Looks from the pictures that you have the 3 piece rims (lock ring ,outer ring and wheel), you can still find people to deal with them. The RH5 split wheels are the ones many shops will not deal with.have seen your model truck with 8.25X 20 tires but most I have seen were 7.50X20. It appears to be a very solid truck so you are way ahead of some of the folks here at Stovebolt.com Good luck and lots of fun with project
