Just thought this might help someone when they decide to build their own bumpers. These were somewhat simple to build and didn't cost that much, mainly time. Main brackets that bolt to the frame are one piece and go all the way through bumper, that way you don't have to rely on how good your welder is. I ended up making main brackets out of 1/2" because that's what I had laying around. Front bumper is 1/4" except very bottom where its 3/16. Rear bumper is 4x8x1/4" tube. I don't have measurements
