First part of the story, I found more power in the 66 after retarding the timing and discovered the clutch slips between shifts and cruising into a head wind at 65/70 mph. I have been putting if off, you know cold in the shed, didn't want to remove the primary cover as the bike has been oil leak free since i built it last year. Weather is looking good and I want to ride my BSA. I bought a gasket with hopes of tightening the clutch screws. One would not tighten. SOOO, I take more apart only to be surprised by this.

They are flat fiber type, no sipes, or grooves. Nothing looks burnt, warped, stained, or pitted. The drive dogs all look nice. Do I reinstall them? Am I missing an opportunity where I will be saying a few miles from here, I should have put new ones in? If so is there some new era clutch plates I should be purchasing? Thank you I dont know why the photo doesnt show.
