the one piece single type 19.5" wheel came on late 50s-? gm box vans(like a bread truck ) & they are fairly rare but can be found. if you want dually or "budd" style wheels look for a gm p30 or p35 box van from sometime in the 70s to maybe early 90s( fritolay wonderbread ). these wheels have an 8 lug bolt pattern & the correct center hole diameter. ratskin you are right the 17.5 single wheels that came on my 1 ton & the 20" dual types are in fact 3 piece. i'd be up a creek if i had to change one! 19.5 tires are much more readily available. these wheels look great on my truck. to me this is the way to go if drive your truck & use it like a truck. changing over to the dual type wheel on the front is a simple matter of finding another gm truck with the hub extenions, they just bolt on to your existing wheel studs. it works for 3/4 tons too. i didn't know until recently that 3/4 tons were available with duals. i used hub extentions from a 54 3/4 ton on my 50 1 ton. if anybodys' interested i have 4 17.5 single wheels blasted & painted with new tires.
