I concur as well. By the way you have U2U Graeme ( if it's working that is) If not I'll send it again.

its the same size to tap the threads for the transit top ball joint aswell .

Yup. Definately...

It's also the size of quite a few of Fords finest wheel nuts

Look on ebay as you can buy one cheaper than buying a tap!

SpookY I've just buggered the thread up in mine and was about to ask the same question!
