I mentioned earlier about the lines on the very tip of the bottom of the rocker panel so when you're done grinding you'll only see about 1/16" of that line. But with the square you can line those supports up perfect.
Those chain hooks on the support bar of the rotisserie allows me to put the edge of that rocker panel in a really nice working position.
The three sizes of drill bits...1/8, whatever, and a 7/16, sometimes I use a 3/8, but a 7/16 is quicker.
You can see where I drilled the spot welds out and also the hole where I drill too much and went all the way through, no big deal.
This is how I break the spot welds loose, with a putty knife and a hammer.
