The +.050 designation tells you this is an oversize guide, used when a head has been bored out from worn or damaged standard guides. Beyond that, our record on this one is brief, and we don't have it tied to a specific model in the files. Bring your head measurements or the old guide with you, or call the shop and we'll work out fitment before you order.
