Well, in looking at everything on the car, I think the essence of the YZ is the magnesium bulkheads (Front, Rear and Motor) as well as the belt drive system.

Working with that. I will try and restore the drive train the best I can, then take some liberties with the other parts. I have some dreams of making a custom 870c chassis with Fibre-Lyte. But that is further down on the list.
As it stands now, I will need to redo the front of the car to properly restore. I think the original owner both didn't read directions very well and at some point trashed the front end. It sounds like the magnesium parts were prone to cracking so I am thinking the front got torn up and was replaced by a RPM front bulk head - fine but I like the original design better - especially if it doesn't crack. Plus I have the mangled front pulley to replace and a general overall drivetrain rebuld to do. The belt seems pretty good, although my tensioner never worked really well so I will have to look up the design intention in the manual and see if it still can work.
I think I will start pulling off parts this weekend. Photos to follow.
