Oops. The guy at summit told me that info....sorry

MelWff

what Really matters is which timing tab indicator You have on Your motor.
It should lay very close to damper's outer edge.
If so, measure Your damper diameter & replace w/ same size.

and complete your profile to include an approximate geographic location.
