Changed the design today. The swing arm was just too long. After getting the AtoZ Fab hinge parts in with a mallet, 3" long 1" bolt, 3/4" washer grinder down to fit, I setup the welding position for the hinge support. The arm was waaay longer than I thought it would be. So it'll be 2 arms now. Tire on one, jerry cans and jack on the other. Luckily I had a 4x4x1/4 piece of tubing 3" long left from the first hinge support in the scraps. Just need to order a second hinge from ATOZ to match.
Update: Almost finished and was able to keep it to 1 swing arm. Just a few more pieces to weld on: jack base, jerry can base, tag holder and lock. Then it's prep work for BDS rust proofing and cover coat.
