Any guidance on my 1970 Duster plans

I did the full FF kit with 1.03 T bars and front / rear sway bars in my 72 340 4 speed. Have the 20-1 and 16-1 manual steering boxes. I put the 20-1 in and did not feel the change to 16 was necessary.

I had the same idea of Auto-X when I was fixing my car up. If you really want to do Auto-X and not mess up the car, you have to put in at-least frame connectors. If you are planing on heavy Auto-X I would recommend putting in the torque boxes, the floor board cross support, from frame support, panard bar for the rear end to keep the rear end “centered”. There is some other trick things to do based off the T/A a/e body race cars of the day.
