<HTML>Upright ribs seperating should be simple.....using a spatula get glue behind all the ribs that have loosened and drill pilot hole through rib only, then using wood screw, sheetrock screws work just fine, get length slightly longer and you will go through soundboard, no problem, just drill enough holes so that you can suck the ribs down evenly going from the shallowest to the deepest crack......Works fine and on an upright, dont worry about the screws going through, if they bother you, cut them off with wire cutters.... tom mc nabb</HTML>
