Any electronic gurus around?

The factory radio on my 1990 535i has the "crackly, staticy, volume knob problem". I was able to dissabmble all of the internals (which is tricky little jigsaw puzzle) except for the volume pot assembly. This is soldered together with some fine connections which I don't know if I could repair/re-solder even if I found a new pot. I can't see any numbers but the back of the pot says "ALPS" (I think) and "JAPAN"

The question is - What are the odds of finding the exact replacement for the volume pot on a 15 year old radio? (Would have to be the exact one, with same pins, push feature, etc.)

If there is no chance of finding the exact replacement component then I will use the radio as is for the rest of it's life, however long that may be. If I can find a new pot, however, I would like to take a shot at replacing it.

Thanks to all.
