I will eventually. I need to do some research on rally cages, because that's what I ultimately want, but not the whole thing right now. I need to figure out how to install SOME of a rally cage enough for me to drive normally, and then when I retire the car finish the cage. The way it looks is that we can't install cages in our car (proper, legal, and correct) without totally losing access to the back seat with the main hoop bar, or if we move it forward enough the main hoop will be right in line with your head while driving, making it VERY dangerous to use on the street without a helmet.
You could tilt back the main hoop, and I would if I was making a drag race or autocross style roll bar. But if I ever wanted to enter a local rally one day I'm sure they are 100 times more strict about proper cages than the local dragstrip.
Obviously this is something I'm also not going to be able to do myself since I would do it with moly. Maybe next year when I get my house I'll have room for a bender and a tig /ubbthreads/images/graemlins/smile.gif
