'83 300D Need help with Clock cct board

Hello,
This is a repost because I got no replies so far and I'm running out of options. I pulled the instrument cluster and the clock in order to replace the 2 capacitors that I heard go bad and I noticed what looks like a resistor next to them that is burned up.
I'm hoping someone with a working clock and cct board can look at the resistor (if that's what it is) and tell me the value, or if you have a schematic that shows the value.
I can't seem to track down a schematic or any information, or even a working or non-working board. Any help would be greatly appreciated.

Thanks,

There will be no schemtics of the internals to a non servicable component. Do you have a picture of the resistor in question? I have boxes of old components.

Just a guess, the resistor is a current-limiting/"fusistor" that limits the amount of current to the clock if something goes horribly wrong (like a shorted motor, chip, etc). Six out of seven clocks I've brought back to life worked fine after replacing the two capacitors; I'd just go boneyard another one and fix it. AFAIK all of the "small" mechanisms that go in the third pod along with the tach are functionally the same.

I have 'sometimes' been able to read the color bands off of a burned resistor through careful scraping with an exacto knife and using a very good magnifier (loupe) and bright light. But Strife's boneyard advice is probably going to be ultimately correct!
