I bought a Stanley J3560 Thin Pattern Service Wrench 1-7/8" and Sunex 97750A 1/2" Dr. 1-7/8" Jumbo Crowfoot Wrench CRV from Amazon. I used the open end wrench on the nut and the crow foot on the stuffing box itself. What worked best with the crow foot was wedging to with a block of wood. The open end wrench fit but there wasn’t much of a swing. I had to keep flipping it 180º after every turn.
