yeh was thinking that but better safe than sorry

i was looking in a haynes manaul and is says a number of locations so i had a look and found number i have just give them the one i can see . its ok they can still identify it now with the number i give them
it prob was on the head under exhaust port but i couldnt get it on ramps to see and the gasket was covering quite a bit too .
its all good thou all they want is numbers
