Thanks Bob, that really helps but I can’t quite make out what kind of nut that is, it looks kind of like the self tapping nut with the built in shoulders like the ones that attaches the quarter window trim (boomerang), instead of an actual threaded nut. My originals just had an ordinary nut like you’d get at the hardware store but there was a lot of wire splicing ant the fiberglass had been patched so it probably got messed up in a fender bender and whoever fixed it used whatever they could find.
It was good to meet and talk to you Tom!
