Too bad your not in MN. I worked in ProMod Drag racing and know a thing or two about fab and race prep, i would love to give you a hand. The jeep speed class intrigues me and it might be the best way for me and a couple of buddies to race at Baja I am thinking if we built one here in MN we could keep it in AZ at my families vacation house and travel for races.
I noticed a dialog about halon systems a couple pages back. If you can afford them and they don't push you over your 4K weight limit i would say to go for one! I have seen a couple guys burn up $100,000 race cars because there class didn't require halon and they were not running them. (one was a supercomp car and the other a fast door car) I had one crewman's daughter accidentally hit the lever in the garage and set off the bottle one time, it was a mess so make sure you keep the cotter pin in the bottle when not racing the car. Otherwise they are cheap piece of mind both from a $$$ point of view and from a safety point of view.
