Paul, On the Quarter Grand the damper heads pivot, so loosen the up-stop rail, (raise it), and use the Renner damper pliers to stroke those puppies back to an acceptable shape. Test for fit. Readjust the upstop rail and you are up and running. I've found that if you heat the plier jaws with an alcohol lamp, sometimes helps also. Regards, Joe Garrett, RPT, (Oregon)
