I wanted a place to mount my jack and I have seen other ideas on this forum so I decided to do a variation from that. I bought a couple of 6"-7" long 1/2" bolts, 6 washers, 2 nuts/lock washers, 3" long SS pipe(slide over the big bolt, acts as a spacer) and some easy to turn black plastic knobs with the nut built inside. First get an idea of where you want your jack, then drill a hole through the 2" aluminum rack tube. Place the bolt and washer through the back side, slide on washer, small piece of pipe, washer, lock washer and then nut. Make sure this is very tight. Next place jack on the first mount, then mark where you want the next bolt to be. Ideal to have one in the front and also in the back. Repeat process again. Place your new bolt mounts through the jack holes and then screw on black knobs. For safety reasons I would lock up the jack.
