This is a budget build as the title states. I am using the scrap I have laying around. I have spent so far $0.00 to this point. I machined the mouting plate for the light bar (no pics). I cut the uprights out of 4x2 rect. 10gauge. I also cut the mounting plates for the bed. I had all this steel laying around. I already have the expanded metal (cage) to protect the glass laying around. I need to get a few feet of more 4x2 and some 3" flat. Here are some pics of what I have done so far.

I was able to find the angle of the cab with this great tool. Digital anlgle finder.

Then I cut calculated how high I want this thing to be and cut the uprights to the proper angle. Remember you are cutting from 90 degress. I wanted the uprights to be at 72 degrees so I made the cut at 18 degrees.

Here is the upright.

These are the 12x5x 1/4" base plate. Notice the holes in this stuff, again more scrap. These plates cover up the front stake pockets. So I will machine a hole in them so I do not loose the functionality of the stake pockets.
