I need to change the hub bearings on a Giant P Elite C rear wheel. Anyone happen to know the right bearing sizes?

I know the easy option is to remove the current ones and check, but I can't get the freehub off at the minute. Seems to take an 11mm or 12mm hex key and I only have 10mm at the minute. I'd like to order everything I need now as I need the wheel fixed asap.

6001 2RS drive side and 6091 2RS non-drive side a good guess?
