SUPER GLUE IT !! Anyhow you dont have to weld the cage together at all. You can have it slip over a tube which matches inner diameter of the bar. Main this to this is the cage is 3 pieces. Top and front and back sections. To install it you place the front part of cage into the top then slip the back section into place then bolt it all down to floor. As long as your front and rear pillars are secure it will hold up to pretty hard flop. This type of cage isnt ment to high speed rolls but on trail rig it imo just as good a job as the all pro and marlin cages. Ill post some pictures of mine tomorrow before I pull it out of my 79 yota.
