Stream stay furler

My furler went to peices as a result of defered maintaince .But,at least I know how it works now,so there will no longer be a reason to defer the maintaince.It's original equipment(I believe),and think Stream Stay is the brand.The approximate 1'' thrust bearing with O-ring seal and captive bearings is no more,and having trouble finding another.Still have the ball race/thrust plate so going to reassemble it with bicycle wheel bearings temporarily.This roller just has a locknut inside that can back off and allow the roller to come free,especially a high friction unmaintained one.I was thinking about peening or drilling above the nut for a split pin but now wonder if this will work harden the peice opening up a new can of worms.Soooo,if anbody knows where to get the thrust bearing,or if I am going to have a work hardening issue,would love to hear from you.
