Be careful, John:
The actual line voltage is not relevant, the motor runs over the mains transformer and gets always the same voltage, no matter if ac in put is 120 or 220 or whatever. So you must get the (at least) same voltage ratings as the original caps show.
(I assume you have the TK 54 "U" version for North America, including 60 cps AC. The german modell has other Cap values.)
There is no start capacitor, both are operation or "Run" capacitors. There are two pieces because the motor has seperate coils for two running speeds: A high speed for 3 3/4 and 7,5 ips (selected mechanically by switching the belt wheel), the other, low speed is switched electrically and use with 1 7/8 ips (with mechanical (belt) setting like in 9,5 position)
I am not quite sure if the caps in your ebay link will do the job, for there are specified as start caps. Motor Run Capacitors are usually larger and come in a tin can, like these (don't mind the value, just example): https://www.ebay.ca/itm/AC-Motor-Run-Ca ... SwanFctkYC
Maybe you should ask an electricy engineer in your region - or you use those in your link- and see if they will last. To be honest, this is the way I would probably take - trial and error
