If it makes you feel any better....
I went to all that trouble with the fuel filler clamps and then said "screw it" when I got to the engine compartment and did worm gear.
Couple options:
1) I have to believe that someone is reproducing those clamps. Just need someone to tell us who.
2) There's a lot of trucks/ cars in fence rows or vintage salvage yards or barns. Just need to find one that hasn't been messed with, get the clamps, and clean them up as I outlined.
3). If neither option 1 nor 2 pan out, take the "screw it" approach. Unless you're trying to win shows...the only person it's bugging is you.
