Here is a pic of the rolling chassis. You just woudn't believe what a trial it was to get to this point. This should have been, in my mind, one of the easiest things to do. I can tell you that I know a great deal about 1979 CJ5 frames at this point! Many thanks to CSP and others who have been teaching me about other
frame years. Quite a few of the lessons I have learned, so far, have cost me money, sometimes significant money, without the benefit of a Professor or degree! You guys have saved me a lot of unneeded expense.
Using the specs from Dave's manual as an example, I learned that the crossmember/body mounts at the frame arch are too narrow (is there a name for this crossmember- can I get a new one?). According to the manual, the measurement from center of body mount to center of body mount should be 31.26" (illustration "K"). Mine is only 29 1/8"!! IF I AM READING THIS CORRECTLY!
To really kill things for me, and make me want to go hunting, the PO installed his "once upon a time NEW" FG tub onto his "Look, Honey, I fixed it" frame. He actually drilled the holes for the tub KNOWING it wasn't right.
Okay... I got a hold on myself! Question... can I cut through the middle of that crossmember, spread the horns to the proper width, and weld in a filler piece?? Seems like it would work. The other part of this deal is that the frame is no longer square... it is diamond-shaped. The left rail is ~1.00" ahead of the right. Why can't I cut the horizontal welds loose on the frame at each crossmember/brace... leave the vertical welds attached to the frame... and pull it back into shape. This would be on the shop floor with suspension removed. AJ says definitively "NO".
