Thanks for the reply & and the links. Your tool link matched my tool link.
However, the part I am going to need is the 'lobed wheel' the arm rides on. The manual calls it the "shift drum stopper plate". Actually I will need the circle plate
behind the lobed wheel. It may all be the same part, won't know until I take it off.
Having used the impact driver before I was aware of the 'tap in the bit' step, which I did. I then succeed in breaking off the tip of my impact bit. Along with having the clutch stack come apart with a few small springs flying out. I won't know if any went inside the case until I get the clutch assembly off to see what is missing. The inner most clutch plates are now hanging out of the clutch assembly. Sh!t!! does not cover what was said when that happened.

So now I get to drill them out. One screw is hosed, another getting close, the third is still fresh.
These are right handed screws, lefty loosey, righty tighty? The manual just said to remove the three screws. So I assume they are normal right hand screws. This is a bad design by Honda. These screws should have been allen drives if not torx drive given what is need to remove them.
Did I do something wrong? The motor is laying on its left side, on the bench.
Pondering this thought:
So back in the day, when one of these came into the dealer for a clutch plate replacement the tech smacked the crap out of the screws to get them off?? One of those 'would love to see that" moments. They must have hated replacing clutch plates.
