Ditto on grinding the o.d. and thickness of the nut end of the wrench but fine otherwise.

I had to grind the business end down considerably to fit the cylinder base nuts on my O-200, but apparently thats normal for any cylinder base nut wrench. Otherwise, fine.

Wrench head OD is too big for O-200. Needs grinding to fit.
