I bought an NA last year, they guy mounted the camlock harness belt system behind the seat on the left panel next to center tray. It looked like a cheesy and foolish place to mount to, after further inspection, it's mounted to the subframe underneath and the main bolt comes out thru the rear wheel well. Not sure if it was welded in place or a Mickey Mouse job. Not a track car, an insurance recovery I'm putting back together. Former owner must have raced it.
