CLUTCH M/C CAP?

[erasjfr@lmera.ericsson.se (Steve Foster ZD/KC)]

I should think that the opening is of the same size / has the same threads as 
MGA's & MGB's?

If so the child proof plastic caps on a lot of domestic product have the same 
thread.
Meths bottles, Cellulose thinners tins etc.
You have to remove the inside part by force....that's the part that fits. If 
you don't
the thing will go on but not come off!
I'm using one of these as my master cylinder cap. The airtight foil works a 
treat to seal out the
air.

Good luck,
