Just spent 20mins using inkscape and came up with this, which I think is but don't warrant, to be IVA compliant.
Just print it out on an inkjet, and use a bit of clear sticky-back plastic for the Blue Peter solution.
If anyone wants the SVG file so they can modify themselves then just ask, though if you can use inkscape it's pretty easy to do your own.

and remeber the sticker doesn't have to be on the cap itself - as long as it is within 100mm of it. ie you could stick it on the bulkhead were the master cylinder goes through - might last a bit longer on there.
what about this from CBS..

i could order 10 or so then send them out at a better price than £6 p&p each....

Whoa, thanks for the posts, have saved the pdf, noted the link and hope to visit scrap yard tomorrow!
Should get it sorted one way or another.
