John on the bed rails is 1/4 x 3 inch steel. cant remember how long but i udes 2 1/2 inch gr.8 bolts. D.S. has the 1" id pipe welded to it w/a hole through it. Passenger side is the same but has nothing welded to it. As for the bumper side 1/4 inch plate wth the 1" pipe welded on the d.s , and i used 2" square tubing welded to the 1/4 x 3 and used another 1/4 x 3 on top with a hammered down overlap so the mount will slide up on to it. I will try and get some picks fo ya.
Hey Walt- nice job- don't worry about the welds, nothing a little grinding, primer and paint can't take care of! Despite what one person so far has said I'm impressed- it looks good an will definitely do the job, $40, a couple of hours and the feeling you get when finishing the job are definitely worth more than a few hundred dollars spent on a factory mount if you ask me.
