1970s Grover Slimline Set

How many of you have a Martin guitar from the early1970s, sent out with Grover Slimline tuners of the day, where the covers on one or more tuners have either blown off or are threatening to? We have here a totally intact, complete set, with all the covers securely in place. Bring your late-60s-early 70s Martin back to its original glory with this nearly impossible to find set, complete with all six bushings and all twelve mounting screws. $149
