The part number I gave you is another different leg kit then the OEM. It is the same diameter then the OEM Premium Leg Kit the 3 legs are just longer. The Leg Kit, Triangle, Ash Catcher and Wheels are a Take-Off of the Red Limited Edition kettle the came out around 2018. The legs are wider at the base so you will also need the Triangle which is Weber Black Triangle part number 67002. You can order them on ereplacementparts.com or from Weber. You will also need 8" Wheels to make it level. The Black Wheel part number is Wheel (need 2) 66997
Now I understand. Thanks for the details. It’s a bit more involved to upgrading the Premium than I’d like. Instead, I’ve decided to add a Master-Touch to my collection. Cost-wise it makes more sense to me.
