Gord,

A 139 tooth flywheel would have been 6v but it would not have been off a 235, which used 6 bolts (as described above, by Dave). It might have been off a 216, which were introduced in 1937, but 235s were introduced in 1941.

Is there a casting code on the flywheel?

Also, Dave's information is for USA engines - there might have been differences in Canadian engine?
