Right, but the only way to be sure is to try it and verify.

Right!

I think the change over happened around 66, so I'm not sure what 
you have. If you send me the engine # I can check, but most 6V 
parts are non O-ring style. The O-ring style flywheel will have an O-
ring groove at the bottom outside if the crank socket. The non-O-
ring parts use a flat paper or metal gasket there. Use exactly the 
parts that you find in there unless it seems clear that someone's 
put the wrong thing in there. Shims for the 2 styles really are 
different (different IDs and should not be interchanged). There are 
cheap shim washers out there which have really bad burrs on their 
edges; don't use them.

Perhaps Russ can tell us which cranks use the paper gaskets and 
which use the metal one.
