Here's a real affordable problem-solver part for folks who collect El-Cheapo hollow body guitars like Kay, Harmony, Silvertone etc. Quality is better than the stock tailpieces found on those guitars. Heavy string bar is 83.55mm wide, 10mm string to string spacing. I measured 105.79mm length from the front of the string bar to the back side of the hinge. Hinge is held tight to the wire frame by string tension. Mounts to end of guitar by the included three Phillips head wood screws.
