Rudder bearings for Westerly Griffon

[DinghyMan]

I have a Mk1 Griffon (1981) and the dimensions of the bushes in the drawings fitted to my boat without a problem? The main thing to be aware of is the dimension of the rudder shaft I believe is actually 9/16ths?

Yep, they are inconsistent, I've seen Mk1's with two Mk1 sized ones, two Mk2 sized ones, and even one of each sized pintle
Rudder shaft should be 5/8" as standard, or can also be 16mm if its been replaced with a metric version
I have a set of drawing showing both sizes that I need to finish & upload to the WOA site sometime when I get chance
