Hey Falconvan, Killer little build you have here. I have been reading it and I can't wait to see you finish it. You were talking about wheels, if you do want to get some steelies for it, try the Dodge pickup 20" spare tires. they have the larger center, and 5x5.5" pattern. you may be able to pick up some centers or you could get get a set of bullet center caps and matching lugnuts.
Just a thought. keep up the killer work!!
