The reel bearings of all things are one piece of the puzzle that you can source pretty commonly (RLS52RS / generic) and they�re not dear. The GA Spares catalogue likely has them, although you can find them at bearing shops, online, etc. Seeing as you are having the reel sharpening done locally, that would be a good point of call - ask them for a pair. The GA spares componentry I am more or less referring to are those specific to the SB model 45; e.g. clutch halves, reel bearing housings, transmission parts, etc.
