The only thing I could find at the junkyards around here were 16.5" wheels off a '70 3/4 ton. Hated to go with them because they are dinosaurs, not much choice. Only problem I ran into was that same old crap of the backspace. I had to use a spacer on the front to get the clearance with my stock tierod ends.
So Bill, seems like we've been around this part of the track 500 times. Are you saying that any 16" 8 lug GM wheel up to '87 will fit without a backspace problem?? Problem now days is assembling a decent set of 5 rims from 25+ year old GM Trucks. All the junk yards around here haven't really been able to tell me what the rims are that they have stacked up in the corner. All they know is they're 8 bolt and that's that!
Sure wish one of the wheel makers would come up with a replacement wheels for the 3600 series trucks that had the proper backspace and centers that would take the stock hubcaps.
