here are a couple of shots of mine. if I hadda made the link to the lift a little longer the cab could be let down a little lower to the ground without interference. the stoppers on each end keep the cab from slipping off plus keep the 2x6 from spreading. a piece of tape on the cab where the edge of the lift bat sits when the cab is level will also help so you lift the cab level each time and no messing around trying to get it just right.
bracing of the cab is also a good idea. fit the doors so the gaps are good, throw a couple of cross braces in, then the doors can be taken off and the cab lifter. that way the cab stays the same, geometrically, and the doors fit when the cab goes back on. especially if the cab is gonna need a little help in the cab mount, floor, door pillar sheet metal area.
