Thanks!!!!Not absolutely sure but think I saw one advertised at British Legends in France that replaces the oil filler cover slotted piece.W I'll check for you and come back.
Thanks again for all your info.Take a look at www.britishlegends.fr you will see several pictures of what I described,under €35,they do ship worldwide but no idea of costs,maybe someone where yo are does the same?
Good luck anyway.
Brian.
Thanks!! The elbow method seems to be more accurate.I checked the accuracy of one if those screw in temperature sensors and it showed 86c at the boiling point of water.
I think you would get a better idea of oil temperature if you put your elbow on the clutch cover.
