[oletrucks] O-ring

["Williams Grant Civ Det 2, 412 AMXS/MXA2T"]

Good morning.  Regarding a 1950 GMC stock fuel system, I am looking for an
o-ring to replace the one used under the fuel tank in the fuel shut off
petcock.  The o-ring fits on the petcock shaft and seals the cap to the
valve body of the fuel drain/supply/shut off component. Does anyone know of
a source or has anyone found a suitable substitute for this?
