    Just get them tight with 1/2nratchet. I used anti seize on whole bolt. You cant break them, tight as you can get them by hand is good.

    I did some digging and the newer one piece style mounts are 210-230ftlbs on the vertical bolts. More on the front mounts if it steps up to 3/4 inch bolts.

    I usually just stall out a GOOD half inch air gun. Never seize the bolt shoulder as well
