Ok, so I'm racing a metric car so it really doesn't apply to me yet, but it will in the future. When you build a unibody car, the rules say you need to add square tubing to complete the frame, right? How do you go about doing that? Do you just weld it under the body or what? I saw it in Steve Smith's book, but didn't grasp how it's done and what you are actually tieing together.

i take the front of the rear frame,open it up like a "c"laying on its back.take the square stock,slide about a foot into the front sub frame,lay the rear in to the "C",and weld the snot out of's pretty straight foward once your in there.

I cut out the rocker panels in my 77 Nova the dropped the 2x2x3 in the rockers and connected it to the front and rear section, you could also run it right on the floor and connect it that way with the 2x2x3. Eddie

I have an 81 Camaro and the front was no problem I slid 2by3 stock right in the frame, the back is behind the floor pan indention where the seat sits. I had to modify my floor pan to get enough room to attatch front with back. I then ran peices off the 2by3 for my cage posts to go down into.Im pleased it seems to be rock solid we will see!!!

if you have a tubing bender handy best thing is to cut the tops out of the rear stub. take some soft tubing bend to fit in rear frame rails then bend 1 1/5 pipe in then install the sqaure tubing. for more strenth and rear weight you can even plate the top and have one stought frame. that is how mine is built and i can put a jack right in front of the rear end and jack 3 wheels off of the ground..
