8.8 swap
Long side is 20" from backside of flange to chunk. Short end it 17&1/8" from back side of flange to chunk. So some simple math puts the long side to be shortened by 2&7/8". I sprayed the tube with machinest dye. I used my 3" C channel to get a lay line. Then i measured 10 inches, dead center on the long tube. Measured 1&1/2 on one side of the center line, 1&3/8" on the other side of the center line. This gets the weld close to center on the tube. Probably the strongest point on the tube for it to be. Depending on where i get with it tomorrow, i may be cutting and chamfering the tubes. I may make something out of the piece i cut out of the tube. I'm tired, I'm going to get some rest.
