Made Them
I had the same problem last year. Dinged rudder was fix with Marinetex and covered with gelcoat. The plastic spacers/washers fell into pieces when I took the rudder assembly apart. I used what was left of them as a pattern and cut the two pieces out of plexiglas. While I was at it I sent the tiller out to have the throughbolt hole filled and redrilled since it was wallowed out by the bolt threads. I replaced the bolt with a slightly longer one to keep the threads out of the tiller.
