OK, back home now with a real keyboard.
So, the first and most difficult part is removing the black clock face ring. I had to search for a very small, thin screwdriver to use. Push it in behind and twist, working around face and eventually it'll let go if you pull on it at the same time. Look at this for a better description of this part:
Pelican Technical Article: VDO Clock Repair
The back of my clock was different than he described though. Anyway, take off the face and store the screws securely (mine disappeared and after searching the garage floor for 30 mins I found them right where they were supposed to be, hiding in plain sight.)
Next, unscrew the two screws on the back that hold the clock bits inside. Now a single wire sticking up through the back of the unit is left holding it in. Unsolder while pulling down and the parts will come out.
I sprayed some electronic cleaner on everything too. 1 of the capacitors was obviously damaged. On the back side, unsolder all 4 pts for the two capacitors. Replace with two 100µF 35V Radial-lead Electrolytic Capacitors. They are marked +/- and both go with the neg pole to the outside of the board (which is marked neg also). Trim the wires after soldering in. Resolder the center back wire and replace screws etc. I found replacing the face ring pretty hard too but eventually it popped back into place with some cursing. Miraculously it is still ticking away.
Hope this helps. Also, for VDO Quartz clocks only.
