Well got the hydro out and cleaned it up some.
The manual from the108 is in, had to remove front brake levers from tranny and grind the lugs for them down a bit as they were hitting the 680s break cross over lever. Also had to drill the paint out of the forward mounting holes on the frame as the front of the hydro mounts further back.
Next will get a clutch assembly mounted and linkage made. Will need tio sit a motor in there to line it all up.
So got a good start, the tranny will then come back out and be built for pulling and painted, and needs a new shifter.
The battery will move up front where the gas tank is and a Smaller gas tank will mount next to it. Stuck the hydro drive shaft in to see if it clears.
A few pics of my progress:
