Those Zenith Chromacolor II can capacitors (22-7126-01) are available from TEDSS.com. The only place I've been able to find them. It looks like Zenith contracted those out to York air conditioning. TEDSS says they're slightly dented. The two I ordered had tiny dents like there were a bunch stored loose in a big box, not crushed or anything.
