Here is what I actually did today.
It was a lot of work, but instead of taking this stuff to a machine shop to have it cut with a band saw, I used my cut off saw and 4 1/2 inch grinder with a cut off wheel. Took about an hour to make all the cuts.
This is the last cab mount I welded up.

I finally got everything dialed in and got some descent looking welds. The other 3 got good penetration but were not as pretty.
Just a quick shot of paint.
Tomorrow I will try to get them mounted and drilled for the stock S10 pads. Have to invest in a hole saw.
Will try to get more pics up as I move forward.
