Hi Mark,
I think I have the most horrible Norvin that I am trying to change. Whoever put it together had no idea!
I have made my own plates, Time consuming but they fit well.I have made two top mounts that allow for movement up and down and side to side so I can align the gearbox to engine. The engine has been chopped and it's got a Norton gearbox. I've just bought a Bob Newby belt drive, so won't have to make an oil tight chain case. Can anyone tell me the thread on the drive side crankshaft as I have to make a new nut to secure the pulley.
