Rubber bushing kit, for 37-note synthesizers which use the Pratt-Read keyboard assemblies (many of the classic Moog, Arp, and other synthesizers used these). Replacing the hardened and brittle bushings in an old synth will restore the key action to feeling brand new! If some keys are sitting higher than others, replacing the old bushings (and bending the mounting tabs if necessary) will even out the keys. These bushings should be installed in the orientation shown in the lower photo. You can use white lithium grease to lubricate the inside walls of each key, instead of lubricating the bushing itself. Only the sides need lubrication.
