I have zincs on the prop shaft, trim tabs and a big one on the stern. Has anyone done a zinc on the rudder?

Our R-25 Classic was bonded to a zinc on the stern and did not have a zinc on the rudder. I think there was a bonding wire from the top of the rudder to the bonding. That should reduce or eliminate the need for a separate zinc on the rudder’s lower exterior surface.
Our C-28 is bonded but not to a zinc on the stern. It does have a large zinc on the rudder. I’m using aluminum anodes so this is what I’ve installed:
R-3-AL Rudder/Trim Tab Aluminum Anode - 3-3/4" Dia. from Boatzincs.com
The stock SS bolt they provide with that anode is too long so I use a shorter one purchased locally.
