I see lots of work in that thing, and if you ever get it finished, it won't be worth near what you have in it. I'm pretty sure those are Firestone RH5° wheels. The whole thing just doesn't have much going for it in my opinion. Farm trucks that have been in a shed except during the harvest are in a whole lot better condition and can be bought cheap. Running trucks can be bought for as little as $1,000. Ones that stop are pretty hard to find.
