Does anyone know the part number for longer Master-Touch legs?

I have a new 18" kettle (I converted it to a MT) and I understand that the 22" Master-Touch has long legs. I would like to buy those legs and install 8" wheels.

I can't seem to figure out what the Weber part number is to ensure they are new longer legs.

Thanks. Don't need the number anymore.
