So I got the RIMS tube bracket welded in place. I also went to the metal surplus store and got a piece of 1.5" tube steel and a 6"x6" plate to build the control arm. It may be a little long, but I wanted to make sure it was far enough away from the heat.
Today I got bored and tore the whole thing apart to put a nice coat of paint on it. The top stayed flat black and the rest is a gloss blue.
