many 6 lugs later rims work
spacers don't, it's the rim width that needs to clear the disc calipre not spacing
the "Rally" style wheels from a 70s Chevy Blazer clear the six lug brake conversion and also clear the track rod end as well. I have these wheels on my '50 truck. The wheels can be modified to accept the original style truck hubcap without too much trouble. There's some more detail on this webpage.
