There's a couple shorter lengths of tubing that need to go in 1 on each side from the tube that goes to the back, I will put a short one from there to the upper shock area then I'll put in a tube from the front X area to the lower tube just for some added strength..... but its pretty much it... need to drop the chassis and start getting ALL the welding done.... I put the rear X brace in because I plan on towing a trailer and the back quarters needed the stiffness
