Hey does anyone know if the secondary numbers on the flywheel, take for example 326- 216 mean anything?? I have three 326's here and one is the 216 one is 42D and one is 324?? do these second set of numbers mean anything? because on inspection they seem to be slightly different.
thanks

 

Maybe some sort of balancing code? I dunno. Shot in the dark.

 

anyone else know?? I think you might be right on the balance code cause some have a few more recessed holes than others and what not? Can anyone confirm this?
