87 300e alternator capacitor value

[Sopicki]

I bought a rebuilt alternator for my 87 300e and forgot to take the capacitor off the back of the core I returned. I can't seem to find one anywhere. Anyone who has a used one wants to sell me an alternator to go with it. I've resigned to just buying one from an electronics store but I can't tell if the cap was 2.2 pfd or 2.2 mfd and 110 volts. I took a picture of the original alternator core before I returned it, but I can't tell from the picture if it was the funny u symbol for mfd or a p for pico. Does anyone know? or have a spare?

Thanks,
