I’ve been looking for a set of decent seat belt cores for my September 2, 1964 Dearborn built 65 Fastback that I can have restored. I finally found a set on eBay for a decent price and acquired them. I have not decided but I’m probably going to have either Python or Ssnake-Oyl to restore the seat belts. My question is about the hard rubber pieces that are on the ends of the seat belts (pics below). I’ve searched this forum and read through many posts but have not found a definitive answer of whether they were present on early (65) Mustangs or not. I've seen examples with and without. Where are these hard rubber pieces typically found? One end? Both ends? What would be correct? Also, should there be protectors (see last pic) where the belts mount to the rocker panel and transmission tunnel? What are the MCA judging guidelines for seat belts? I'm trying to get this correct.
