Well finally decided to retire my car as my "Daily Driver" to my track day/weekend car. Stripped the interior and found more rust as I went along. Places with rust: firewall under battery tray, driver side floor, passenger side floor + frame rail under seat.
I already have my new floorpans and i'm going to start cutting out the old floors along with the old seat mounts. Before I weld in the new floors heres what I have planned and need some opinions:
1. remove old frame rail under front section of floor pan.
2. make a new frame out of rectangular tubing starting at the t/c location all the way to the rear subframe.
However, I want to run the new frame rail higher than most people have done it. i'm thinking of running the new frame rail the same height from the ground as the rocker pannels because I want to weld in some square tubing from one side of the rocker to the frame rail, then from the rail through the trans tunnel, connecting to the other side of the frame rail, to the other rocker. This square tube will also be used as my seat mount and done twice across the car.
3. weld up a square tube connecting both sides of frames and rockers used as my new trans mount ( i'm going to be shifting my engine and tranny rearward)
4. Lastly, I want to weld up the floor panels outside of the frame and tubes ( frame will be seen from inside, I know sounds weird) so the bottom of the floors wiill be totally flat.
Does this sound do-able? I'm REALLY trying to be able to actually tie the entire center frame section together. I don't see how I can do that if the new frame rails run below the rockers and floor pannels.
