I have a 66 Redeye that I need to re-wire. Actually just picked it up from the repair shop (wanted the tension mechanism replaced but they couldn't get the part) and the guy there mentioned the wiring should be replaced. Said to him since it was just simple lamp-cord wire - shouldn't be a big deal. I don't know how much (if any) soldering would be involved - should be a matter of stripping off the casing of the new wiring and winding under the appropriate screws. Won't have time to really play with this machine for a while.
