Forgive me asking this but I couldn't find an answer in after a search.
2005 Roadster, just carrying out a service and want to replace the lower grease nipples, they are set at 45 deg which I want to keep, but on removal I can't work out what thread they are, they are parallel and measure 6.36mm diameter on thread, i.e. 1/4" so I'm guessing BSF, is this correct?
