I use nothing but double locks. You really only need 2 wrenches but 3 can be handy. The 7/16 is the one that needs to be ground thin but sometimes the 1/2 needs it also. I simply tighten the lock slightly securely against the lifter and adjust. If you want to go up with the adjuster, hold the lock nut and turn the adjuster. If you want to go down, hold the lifter and turn the adjuster. Once you have the adjustment close, lock the nut securely and make the final adjustment to get them spot on. I can adjust a set in about 30 minutes from all being out of adjustment by .070 (new) or more.
