Thanks Steve, I ordered a catalog from Jim Carter the second day I got the truck but haven't got it yet, I'll take a look.
Keep my name handy will ya, if you find the 17" rims and want to dump the 15" I might be interested, only problem would be the distance to ship them.
'78', Never heard of "radial tubes". I need to check with our local truck/tractor tire fixer-upper guy and see what he knows about using tubes with radials.
I still need a spare wheel.
