Spawn, any pics of your buddy's car with the hood up showing the receiver unit for the hood pins he used?
There the ones in the photo, the wire with coil ends. you screw those in the core support and the twist locks grab those. you don't use the black angle brackets as those were for the original 68 KR's as are those twist locks. Those are replacement units for the original 68 cars. and the core bracket needed the angular extensions to use the locks.
