70 dart 470 ci drag car build.

Oh also when I'm welding in the out riggers do I have to use an entire 6 by 6 eighth in plate or can I just use 3 by 4 ?
Crap, I thought this sent an hour ago !
Again also, the bar that is going down by the main hoop is there any particular angle that has to be for certification?
One more thing for that "D" bar. If you're building an SFI spec cage, look up those specs. I just went by NHRA for mine, and that's where the screen shots above are taken from.
