MNSmith: I took 2 4X4's and 2 2X6's and screwed them together square. Had some old cast iron casters bolted them to the wood frame work. Laid the cab on it's back (carpet between metal and wood) roll it all around the shop and 4 sides (minus doors) are easy to work on.

popcorn The Truth is Out There (for my 59 spin it around instead of walking around it) Need measurement to build I'll get it for you. Ben
