Yes the clutch was and still is working fine. I have only seen yours, mine and the one in Phil's video and they are all fitted the same way round.
I looked at Phils video and did not see text on the disc, another oddity. I puzzled about the three extraction/draw bolts in the plate that hole the Centa into its bellhousing. Phille said they are 3/8 BSF - 20. WOW, finding those in the USA is going to be tough. They are close to 10mmX1.25 but apparently not, according to master Phil.
