If the clock takes the same bulb as the idiot lights, that may be a tricky one. I struck out when I brought one of those to a parts place to match. That was a long time ago, now I'm thinking about it--not sure if their selection of tungsten bulbs will have gotten better or worse since. Been a while since I had the auto hvac head out of mine. IIRC there's some kind of cover on top, with the bulbs under it? They're run off the same illumination circuit as the rest of the dash lights, and the LEDs I've put in my dash switches dim just fine, so LEDs should work just fine in the HVAC head. Might take some screwing around to get the illumination even, assuming it's got the same light pipe setup as the manual head. Might need some kind of diffuser. I would be a little surprised if the bulbs are a common size that you can find drop-in LEDs for.

You can buy an extra front one and cut it in half to make your own for the rear doors. It is 99% close enough for most people. Maybe test with one of the old front ones first.
