Well I did search but didnt come up with much for cages in a truck. Im about to build one in my 85 k30. I plan on doing it pretty simple for now, basically a tube going up in each corner, two tubes going across the floor boards to mount a seat and then some triangulation all though out it. Not sure how many places it will connect to the frame, I guess just four? Does any one have any pics of their cage in a truck cab? Or any tips?
