Good info, Steve. Earlier years, of same belt types used 3 styles known as the Deluxe 1, the Vinyl 1 and the Type 2, as shown. But really, the Vinyl 1 was just the Deluxe Chrome with colour coded Deluxe metal receivers, not to be confused with the extended, plastic receivers of Type 2, usually black or coloured, never chrome. It used to be in the top-right of the diagram where now a blank area. These were interchangeable with each other.

There's also 3 types or rear anchor bolt used for the seatbelts, the simple answer is that you need the type that's fully threaded with no shoulder as they screw in all the way tight, not allowed to pivot.

Plain hex/socket head will work but the Torx head is original, T50 from memory, same as bucket seat latch studs, but not the same bolt style.



Edit: Just saw it also has the Vinyl head version of Deluxe 1 on diagram, just rearranged, so ignore the extra info! They don't have to match the front, just have to be a matching pair.
