Got my gas tank skid built:
Actually had posted this up in bigred1969's post:

but wanted to keep my projects together in this thread.
I started by using some steel strap and bending in in under the gas tank and bolting in through the crossmembers to hold the gas tank in place. Sorry no pics, just bent 2" steel strap.
Then I welded an angle iron crossmember in the back of the Jeep, welded in 5 studs that drop down from the top:

As you can see I drilled out another piece of angle and slotted the holes that would mount under the skid crossmember.
Made a "frame" for the gas tank skid with angle iron by cutting and bending it, then welded the end pieces to the cross brace, basically making a skeleton for the skid.
I bolted up the skeleton in place to the frame, then cut plate for the back and bottom and tacked them into place.
With the 14 bolt, I had to notch out quite a bit so it would not have clearance issues. I braced inside the skid with some angle to give it strength. As you can see I simply bolted it into the crossmember above the rear axle.

Actually I welded studs so when I go to install it, I slip the two studs on the front (? or rear depending on your opinion of how to describe it, lol) . . . okay the end over the axle . . . sllip the studs into the hole on the crossmember and that holds that while you simple slip the other side over the studs welded into the angle with the studs, clamp it with some vice grips and its in. Put the nuts on it and it is installed. This is SO much easier to install than the one I made for the TJ!!
All in all, I'm happy with the finished product. Some of the welds got ugly 'cause there was so much to weld I know I kept bumping into the duty cycle of the welder.
