Mac 22 rudder gudgeon replacements

Venture 22 Canyon Ferry, MT
If anyone has replaced the stainless steel rod hinge for their rudder with the gudgeons that Blue Water Yachts sells, I have a couple of questions:
1. Do the hole patterns line up so that it is a direct replacement?
2. Do the gudgeons have a hole for a cotter pin to hold the rudder in place?
Thanks!
