The Grover® deluxe machine heads are mounted three to a plate for the vintage look that has been popular for decades. The stamped back plate provides a sturdy base for mounting vertically or horizontally on the head stock. The housings are securely fastened to the base insuring proper gear and worm alignment for accurate tuning. Bushing and screws included.

Please Note: Grover tuning machines produced prior 1985 use different specifications for threading and shaft sizing. Current production replacement parts are not interchangeable on vintage (pre-1985) Grover tuning machines.
