I did some googling on the subject and found some REALLY neat options.
There are endless options once you get looking, however, some of the best ones are EXPEN$IVE!
You can get the FMS ones. They are nice pieces and are SS. I don't like the idea of lanyards and bought a set of billet UPR pins that have a spring loaded circular snap ring on the pin that keeps tension on the pin. You can see them in my avatar pic.
IMO they are essential when you have an aftermarket fiberglass hood to keep it from flying off. Some people have been lucky and never experienced the hood coming up. I would never install one without them as piece of mind.
Ahh, fiberglass. I saw where a newer model Mustang could pull the pin out of the radiator mount frame during their initial races. There was too much under hood pressure at speed. I have never heard of it on stock fox stuff. But it makes sense now.
