I finally found a knowledgeable source for sickle parts. It's not like your average 25 year old at TSC, Agri-supply, etc even know what a sickle mower is. The parts guy at my JD dealer knows about them, but parts from JD are very limited for 40 year old mowers.

I hope this helps some of you guys. The best part is that the prices appear very reasonable and they can ship the same day.
