Went to look at a '55 Chevy the other day. A 210 2-dr wagon...no engine...but was a 1970s hot rod. Not the completely stock builder I was hoping for, but more HAMB-friendly. Old hot rod, uncut body (great fenders even)...good gasser starter. Anyway - I wondered about the wheels. Cool thing is, it survived with the only mods being... little cutouts in the inner fenders (for headers)... 4-speed hole in transmission tunnel...extra guage in dash metallic repaint way back... 1965 GTO seats (still have the orig. upholstery!) blue shaggy headliner! ...AND they didn't even radius the rear wheel openings...RARE on these '55 hot rods from back then... ...& BIG & little mags! ==== Anyway - what are these slotted mags? I took some pics... ~There are 2 of the WIDER ones, (but according to the tires sizes they are (1) 15" and (1) 14". ~They look to be about 10" wide. Can't be much narrower. And the valve stem is back by the slots. Not at the bead. ~The NARROWER ones are 14". They don't look much over 5" wide. (?). Again, the valve stem is BEHIND the slots, not at the bead. Unusual? ~Super collectible? Or just some old "U.S. Mags"? THANKS!
