if you still have your original condensers, the guts can be taken out and a modern film style cap installed inside it. The mount on a Zephyr cap is different than regular OMC caps so it would be a bonus to use the original can with its mount to hold a replacement cap. Digikey has the needed caps rated at 0.10 uF which your motor requires. They can be found here: https://www.digikey.ca/products/en?x=23&y=19&lang=en&site=ca&KeyWords=bc2607-nd and you can change your choice of country by clicking on the three bars in the top left.
Whatever way you do it, get ready to do some soldering as the leads on the original Zephyr caps are quite long and any replacements will need the leads lengthened.
