Chrome plated steel. Portion of arm that fits into the vibrato measures.19"/5.01mm. Fits many Fender of Japan reissues exactly. Before you buy this bar call Fender Customer Service to determine if this Fender Part Number will fit your specific guitar. I guarantee this bar will not fit old '60s-'70s original Fender Mustangs; it is too large in diameter. This arm fits only modern reissue Mustangs; it is too large (.198") to fit old original '60s Mustangs. Fender does not offer a new arm to fit those old guitars. Chrome tremolo arm with white tip for Classic Series '65 Mustang and Jag-Stang® guitars.
