NOTES for the 965, 975, 975CS, 975CSLD, 975LD reels ONLY:
On these small International series reels, the spool bearing attached by pin to the left side of the spool. Penn did not intend this to be a serviceable part, but it can be replaced if you are very careful. You can tap out the pin and replace the bearing with 55-965. (sample image is the 965 spool)
BE CAREFUL not to damage the pin in any way – it is not replaceable and you’d end up needing the entire spool.
