Stock replacement parts and options listed on these pages will fit the 2760 Steeler fulcrum tremolos only. Discontinued in 1992, not all parts listed in the diagram are available. Only the parts shown below are in stock. FYI: there were 2 different types of arm module used... either the arm hole was actually drilled and tapped into the main block itself on the first version models and later models had an arm module block that was attached to the main block using 2 machine screws (see picture).
