If they did mark them then you could go to your local electronics junk store and buy them for .25

Ive used many times with good results any caps rated above 10-12 volts and at least 2000 microfarads.

Ive had a bad experience using generic caps on my LRP TC with mod motors. With a stock motor you might get away with it.

Im not at home to give you the exact specs, but if i remember correctly the original cap is Matsushita/Panasonic FC Series. Check your cap to see the exact voltage and farad rating.

The original cap has a big gold stripe on one side. That is the negative pole.
