    My TSM says 19 ft/lbs new. 16-26 ft/lbs is the in-service spec. They're only 5/16" bolts, so they don't take much. Remember to tighten the pair down evenly, if one side has pressure you can crack them if they have the all aluminum bridge.

    If you need a tool and don't buy it...
    you'll eventually pay for it...
    and not have it.

    I torqued them at 23. Pretty good guess.
