me and a buddy did this yesterday. it's made out of 2"x2" square tubing. the steel is about 3/16" thick. it's completely welded together and to the frame. took us about 3 hours start to finish. all it cost me was some blood, sweat, time, and the leftover steel. i didn't even pay for the steel. another friend of mine hooked me up with it. he just wanted it out of the way!
