100MFD 55V

Hi, I've got an electrolytic I pulled from my TU56 drive because it had a big crusty electrolyte extrusion through the vent plug in the top. The capacitor is marked "SPRAGUE 100 MFD 55V - 60CY A5030". It is 2" in diameter and just over 4" tall, with two solder lugs on top. I think they are connected to the drive motors. I have looked for replacement electrolytic, but they all have way more capacitance or way more voltage rating, and are nowhere near the right physical dimensions. Is there a source for exact replacements? If not, should I just get one with the right diameter for the mounting clamp and the right capacitance, but some huge voltage rating, or is the voltage rating more important and I should beef up the capacitance instead? Or do I have to get both those right, and substitute a little dinky device? Thanks! Vince
