The caps in my case are 1000 µF 10v 105°C radial electrolytics 8mmx20mm. I found an exact part match at Digikey.ca (68¢ each and postage was $8 for four and a few other components for another project).

Your components may be different but Digikey is a good place to start.
(On a ludicrous note, the same capacitor is available through amazon.ca for $13.99 each plus $12.49 shipping from a affiliate!!!)
