Yep, I'm following you! The clutch disk doesn't seem to be giving me problems, no slipping, no odd noises, no loss in performance. I'm not sure what else would be noticable if the disk was damaged/broken. The throwout bearing isn't making any noise, I know it's supposed to be really noticable if it's worn or damaged.
I really wish there was an inspection hole, but I've yet to find one.
