The bolt holes in the new pintle are intended to align with the holes in your old rudder. But since the rudders are hand made, variation in thickness sometimes introduces a variable that causes misalignment. It may be necessary to fill and redrill the holes in your rudder with epoxy (see "May we also suggest" below).

Pintle diameter: 3/8"
Pintle length (overall): 2-7/8"
Pintle length (extension below strap): 1-7/8"
Distance between mount holes: 2-1/16"
For rudder thickness: 1-1/2"
Width of strap: 1"
