In both cases, another thing to look at is the rubber hose. They swell shut on the inside over time. So check to see if the push rod is moving when the peddle is pushed.
On the 5 speed, and I'm working from memory here, I think the bearing needs to be 30mm thick. But maybe just with 228mm. So the question for IE is: does that one work with 215mm and 5 speed. There is a procedure for checking push rod movement on the 5 speed in the shop manual, or in previous posts. I recall one from Hack Mechanic went on for 8 or 9 pages and covered every possible clutch problem known to man. If your bearing is too thin, the clutch won't release. Ask me how I know. But it could be something else.
