Hi Tony:
The tire valve stems for modern automobile tubeless tires are a perfect fit and have a nice thick bottom to cushion your bonnet!
I use the shortest ones I can find and you can gets lots of free ones at your nearest tire shop as they generally pull the old and chuck them out when changing tires. (You also have two spare valves under the bonnet should you ever need them!)
Would you consider sending your hi-res photos of the data plates to me as I have a chum who is an amazing digital artist who can create new digital masters from good photos. We could then post them to the resources page (with Hanno's help) for all Ford owners' delight.
Mike
