i just happen to have a 139 tooth flywheel sitting in the garage.
[on edit]Bill, I just noticed that your pic shows the caliper spanning 9 teeth. We'd need apples to apples here.

[on another edit] I see that you started at 1, where I started at 0 in my count. I'll go take another pic to repost. Standby.
[editing again] OK all fixed now. number of teeth match in both photos.
