Jim Coleman Jr. makes lag bolts with a hex screw threaded into the top of the screw and pinned in place with steel pins. He needs the diameter of the plate holes, the thickness of the plate at each hole and the original distance from soundboard to plate underside. He will turn down the head of the lag head to fit underneath, set the height of the hex screw so a cap nut will secure the plate in place. These bolts can be adjusted from the top side of the plate with a hex wrench after the plate is in place and can even be adjusted after stringing to help improve tone a fraction. Nice neat thingees, about $11 for each. I just love 'em. Newton PS Loved them Coleman folks.
