I am building a couple of track cars and I am trying to find a source for some hardware for mounting the shoulder harnesses. What I am looking for is usually called a footman's loop and was used by Porsche on some of their race cars. Sometimes it was a formed wire loop, sometimes it was a bent piece of sheetmetal. It looks like this, more or less:
I figure that a version of this has been used in aircraft over the years. Maybe military, maybe in helicopters, maybe in something old. I'd like to find a source for these, as the ones you can get from commercial sources or army surplus are basically cast pot metal and not suitable for my application.
Any and all help appreciated,
JR
