Nothing really exciting about this part. Go over the frame and make sure everything is the way you want it. Clean up any weld spatter. Inspect all the welds. Overall, I think everything looked really good.
I did want to make a couple of small changes. I didn’t like the inboard seat belt mounts. I didn’t think they were strong enough. They probably are, but I can get a bit OCD about that stuff. So I welded on some additional steel plate. My welds are not pretty, but they’re strong.
I also welded some #10 studs here and there to use as grounding points.
I gave the steel a good scrub down, and then wiped it down with paint thinner. I painted it with Rustoleum, Regal Red. I used a jam gun that I bought at Harbor Freight for $6 on sale. Did a decent job for some one who’s never used a gun before.
