Thought I'd share some truck porn.. I made these from 3" 3/16 wall square tube. Radius drilled the holes so the rear would not move forward when using the upper holes. I then cut off one end. Ground the stock rivitheads off two at a time and knocked them out. I then redrilled the holes with a 7/16 bit as the rivits were just shy of that. Once out, I took the stock brackets and set them inside the new ones. They fit inside perfectly. Lines them up and drilled the holes out in my mill (drill press would be fine). Installed them and this is what you see..

Now I need to set pinion angle. As I figured every hole up is 1* of pinion change. I'll now how they work with in the next week or two..
