Found this deal while messing around....
First one on the page, the 429. It doesn't have the tail releases, so it'll be permanently strapped up, but they're damn good harnesses. I've got a similar one in my car, and at that price its well worth it. I paid almost twice that. Perfect for AutoX use.
It goes without saying, but I'm going to say it anyways...
DO NOT use them on the street without rollover protection (i.e., a roll bar or cage).
