I kept looking at that map box hole in the subpanel and finally decided to dig in. I put angles in either side. Plan is to have folded 0.04 sheet on either side mounted to the angle. This will screw to the chassis for the gtx45r on the sides. The fold on either side will make a mount point for the gtr20 to sit on top. I’m using a scrap of j-channel to brace one side higher. I’ll post pics as I go but here are a few as it gets built up.
