Trying to figure out what to do to my tailgate? Its a 73. I'm not sure what year they started with the the crease(lack of better word) at the top of tail just below the window. I'm sure this is for the added strength. As for my 73 the tailgate has about a 2in crack of center to the right a little. Approx above where the spare tire mount would be. Currently I have no spare tire mount and am planning to add one. Should I weld the crack and reinforce the tailgate by maybe welding thicker metal inside of tailgate where the crack is or get a newer tailgate. Problem is I like the older looking one which is smooth at top no crease like the newer(late 70s early 80s). Also can anyone suggest a spare tire mount. I noticed one on a jeep cherokee that mounted to bumber only. Looked really cool and no stress on my old tailgate. Any suggestions?
