Remember that the steel plates wear as well Mc, the info on the thickness should be in the manual, it gives you a min/max thickness so make sure yours are still within tolerance. I have a micrometer that I use for this, only takes a few minutes when you have it apart and saves you a lot of swearing if you rebuild it and it still slips.
PS the 2 Suzuki's I had, both of those had minimum thickness on the steel plates so they rattled like a bastard once I got them unstuck.
PPS looking really nice Mc, what happened to the other 2 you were thinking of?
