This shares a name with this guitar's bridge system, but is sold for older and reissue Mustangs specifically. A parts seller has confirmed the two generations are not simply interchangeable, so do not assume this fits without checking first.
Why we say this
Sold as a replacement for vintage and reissue Mustang models. A parts retailer selling the American Performer's own vibrato explicitly notes that fitting it to a standard Mustang requires an additional routing step for the fulcrum plate, confirming the two generations are not interchangeable in at least one direction. The reverse fit, this vintage-spec assembly onto an American Performer, has not been independently confirmed either way, so treat sharing the same product name as a coincidence rather than a guarantee.
