This is VERSION 1. I plan on road testing it for vibration and rattles for a week or so then cleaning up the design a bit. Bottom is two pieces of 4"X7" 1/8 sandwitched together. Drilled out 3 .5" holes where I welded in studs to catch 3 of the 4 holes at base of jack. 4th hole left smaller for lock. To brace the top, I had some scrap 1" square and ran it across with a bolt catch. It is kind of for now but hope to improve the looks if not the design later.
