I had exactly to same problem with the same part/project with Pelican. Seems they don't read Wayne's book at bedtime ! Since they couldn't/wouldn't help I abandoned the attempt to upgrade the clutch. It would have been a nice profit for Pelican and they just couldn't be bothered to check with Wayne. Strange because in so many other ways Pelican are just great.I think they should hire you are their "oddball Tech question guy" !
"When I attempted to "Upgrade" my 986 "S" clutch disc with a Pelican sourced 987 "S" disc as suggested in the 101 projects book, I discovered the input shaft spline is different & incompatable. NoOne I could get on the phone was of any help. I suggested they ask SSF their supplier to compare the 2 discs side by side, but they wouldn't. Finally I had to buy a 986 disc & wait over the weekend to get it. A week after I first reported the problem Bob e-mailed me & said if I would send him the paperwork & explain the problem AGAIN, he would "look into it" Too lazy to ask any of his 3 co-workers I had already talked to!
