I bought a package of 5 bulbs for my clock from my local Ford dealer less than 2 months ago, so they are still available. They came in a package of 5 - no buying just one. The part number on the package is "E5RY-13466-BA". It was ~$20 for the 5. They didn't come with the little green rubber cover, so if you like the color of the clock, don't toss your old bulb. Otherwise it'll just be yellowish numbers that are kinda bright, even in the daylight. That's what mine looks like now because the bulb was burned out when I bought both my SVTs, and the latest bulb has been misplaced - I have no idea what it looked like with the little rubber thingy. The clock face pops out - use something plastic to pry a corner gently, and has two or three little retaining clips once you disconnect it from the dash. You should be able to see how it comes apart and how to replace the bulb from there. If you have big problems pm me and I'll email you some pics. Good luck!
