While we are on the subject, does anyone have one of the 'Power Options' terminal set that snaps into the fuse box. The 66 one that Walt posted has it installed and the 65 one on the left does not have it. One of the terminals is broken off on the one in one of my cars. The box only had that part in it if the car had PW or Pseat from the factory.
This is what it looks like, it's the one on the left with the fuse holder and 3 terminals. Don't know if there's a version with 4 terminals.
These were blasted and replated with a zinc 'Copy Cad' kit from Caswell plating.
