Ian, very possibly. I bought 6 of your wheel bolts and a gear indicator plate from you at Stafford a few years ago.The inspection bolts are the the same as the B series rev counter gearbox bolts without the lock wire holes and just a bit longer.
Random...
The bezel has protruding brass 'tags' (4) around its lower edge which are bent outwards behind the switch plate after the ammeter has been inserted into the hole...The ammeter also sits on a very thin 'O' ring which is placed under the bezel before fitment into the switch plate...Ian
