I am in the middle of restoring my 75 280z and have a few questions im hoping you can help me with! I am doing an LM7, or 5.3 v8 build with a Camaro T56 6-speed. Currently, i have scrapped most of the underbody off to clean it up and get to the rust, and all of the rubber coating off of the floor on the inside. Behind the fenders i have noticed, by the door hinges there are a couple of spot welds for the fender/main body piece. I was thinking, that could really be strengthened up with a fresh weld, which got me thinking: Im cutting out the radiator support and welding in tubular, and making custom frame rail and motor, strut tower/firewall braces which should help a lot. I am also going to have a partial/custom cage. What other spots on the car could use some good welds to help strengthen the shell, due to running a 600+hp v8 turbo setup?
