Put the bench in place and then using a small hydraulic jack and some
shim packs made from say 1/4" plywood, (The shim pack can be say 2"x6"),
level the bench.

I would think that 1/4" is way too thick to make fine adjustments on bench
level. As little as a 1/16" inch can make the difference between rock solid
and wobble (depends on how far apart the legs are but not much).
