: I have no pictures, however if you go to the One Ocean Kayaks home page,
: lower on the page is kayak rudder plans and kits. Click on that and you
: will see the mounting method, just no dimensions. I have tried contacting
: them but have had no reply. I imagine I could get pretty close just
: looking at the photos, knowing the length of the through bolt and
: estimating from that. I would just rather start knowing exactly what I
: need.

This is how to "legally" obtain the exact measurement information:

"Customers who purchased the Rudder Plans or the Rudder mechanism Kit can take advantage of the FREE On-line Manual that shows the entire construction procedure in the minutest detail and in 136 photos and large close-ups.
The manual shows carbon fiber, fiberglass and epoxy lay-up and making the rudder using the plan templates. All shaping, drilling and assembly of all remaining parts is described and illustrated in the manual as well. The mounting of this rudder to a kayak is shown in the Kayak Shop pages. All composite components are illustrated in the Rudder Construction Intro."
