I use several vibration isolation mounts in building generators. A stocked mount that should fit the bill is 1" in diameter, 3/4" thick, 1/2" long 1/4-20 studs, max compression 44lbs, & 15lbs shear, that's 176LB for four mounts. They work well for the instrument panels. They are $2.80 each. Here is a link to the vendor:

McMaster-Carr has a number of mounts as well.
