Aaron and Rob what you both said is exactly what i remembered and told him. I never seen them before either, so he showed me a pic looks like what you showed but it looked like it was topped with chrome or made of metal that was chromed. He also showed me a build sheet with 3 codes for seat belts, they are
AK1, A39, A85. I had told him, none of these were dedicated to the cups as far as i knew. He said it might of been in a package and i agreed with that but still wasn't convinced, because i never seen them ever.
As far as the cruise control, i said exactly what you said that NO SS had it because of the pump. He said he had no proof but seen it and the unit was mounted on the frame below the pump. I was guessing dealer install also because i remembered Bruce saying he installed his.
He was a great guy, his name was Mike, very knowledgeable from his experience with rebuilding our Montes and others (I seen pics, beautiful cars). I tried to convince him to stop by the club but he wasn't interested.
