Home fab front bumper - 2" OD tube ~.120" thick (just under 1/8") - I'm going to run 3 driving lights on the front & I may try to retro fit a winch tray on there yet - under the front bumper mounts I also have the Front Range Offroad front crossmember reinforcement welded on, it's 1/4" plate that'll prevent the crossmember from bending if hit and also prevent the bumper mount nuts from pulling through the factory sheet metal if
mounted with 3 bolts from the front on both sides + the 2 tow hook bolts under the front frame, all mounting plates are 1/4" - the verticles off the front bracket needed to be "squeezed" a bit then cut flat to fit between the 2 lower bolts, the front mount plate extends up and covers the body cross member (in a frontal collision the mount plate will hit the crossmember) - the bottom brackets are bent and the tubes welded on from the side to fit in the body mount pocket
Home fab rear bumper - 2" OD tube ~.120" thick (just under 1/8"), 1/4" mount plates (same as most receivers) - mounted with 3 bolts from the side & 1 underneath on both sides - future plans might include side guards and dual swing outs (one for fuel/water cans & one for an extra spare) - originally I copied the pattern for the mount plates from a tow receiver and just extended it to "capture" the main tube, after a 1" body lift to accomodate the radiator for the 7MGE I needed to raise it to get rid of the bumper gap - thats why the side plates are in 2 pieces now, when I get time I plan on welding some bar to bridge the 2 and prevent the whole thing from rotating downward when I tow
edit 5-25-08 - Got a bit of work done to the rear bumper to finish it off.
Added side hoops

linked both side plates with some small square tube

previously I had a 90* bracket bolted onto the side plates that bolted onto the bottom of the frame rail - now it's welded 1/4" with gussets at each end

finished product
