Question Ruud UAND-060JAZ (7307) Condenser Fan & Capacitor Help

I am looking to get some guidance on what exactly needs to be done in order to properly replace the fan motor on my Ruud UAND-060JAZ (7307) Condenser. Specifically, which capacitors to buy and how to wire them up properly.

Based on my research using the Ruud Parts List, I need to pick up the following:
Fan Motor
Run Capacitor
Start Capacitor

My confusion is that recommended Run Capacitor model appears to be a dual run, which I thought means that I don't need a Start Capacitor. Why would the official parts list recommend that I use both?

The current setup does not use a Dual Run or a Relay.
I have also attached reference photo of the current motor and the current capacitor setup.
Any guidance is appreciated!

Current Fan motor that needs replacement. The Ohms read properly but the bearings seem to be shot.

Current 2-capacitor setup.

You need two capacitors, one for the compressor and one for the condenser fan. It can either be two separate capacitors, or a dual capacitor (2 capacitors in one can). Depending upon what condenser fan motor you purchase, the fan capacitor may be a different value from the OEM capacitor value. Often, fan motor replacements are somewhat generic: match the case style, voltage, HP, and speed. I would suggest that you don't purchase the fan capacitor until you decide what motor you're going to purchase. There should be a sheet with the new motor that tells you what value capacitor and how to wire the motor (may be slightly different from the old one).

It looks like that condenser was modified for two capacitors.
I had a similar model. There was a big dual cap in that hole on the right.
Your current motor uses a 10uf at 370vac too.

Your "linked to" motor is a three wire unit and wires the same exact way as the old one.

I'd pick up a spare contactor as yours looks well used.
