Credit to Bounty, even the tube part,we just stood it off to let the junk fall thru, here goes. 4 x 4 x 1/4" angle.You need 10' total. Mark in place,then cut to wacky angles with plasma torch. Drill 8 oversized 3/8" holes. 10' of 1 1/2" square x 1/4" wall steel tube. We have a cold saw so the cutting of that heavy tube was not too bad. 45 deg where they hit the angle iron and 22.5 where they meet at the corners.Spacer tubes are 1 1/4", just enough to get a tweeco welding gun in there. Most important part is to grind big
1/4" bevels on all parts so you can grind the weld flush without losing strength. Grind it all flush with a 4". Paint with rustoleum, wait a day, wait another day cause its cold. Bolt it up,found some black 3/8 button head cap screws and put a rubber weatherstrip at the top of the angle against the body to keep the agua out. These things are quite heavy but I'll bet functional. 50lbs each. Total cost for both $55 material 6 hours to build and install.
I need to do the TJ but it doesnt look so straight forward.
