I just finished the one that is on my '96 GMC 3500. If you give me some dimensions and an idea of what you're looking for, I might be able to do up a cad for you. Let me know.
The attached is the headache rack, plus a rear rack a built to allow me to carry long (and heavy too) items above the cab and bed. I have HD bed rails (which I made) that the headache rack is welded to at the front. The back rack bolts onto the rails near the tailgate. When not in use, it bolts to the front against the headache rack. I'll try and get some pics of them on the truck.
No special formula.
I just measure my heigth, bottom and top width, lay it out on the bench to find my angles.
I made the spider body from a block of aluminum. Hand ground all the details. The legs are individual pieces of .250 plate bandsawed and ground to suit.
Usually I just blow up pictures on a copier, transfer them to my material and bandsaw cut the details from aluminum plate. The spider web is on my truck and can be removed for other details.
The stars on the Patriot one should look familiar, they are a transfer of the Miller Welding star.
Thanks for the positives! I spend a lot of time on these things.
