@MacEggs , the part number is 63050.
Thinking a white hubcap might look good with these wheels on the Ivory.
Just a heads up for all: Weber CS is getting to be a pain in the a$$, when trying to order by part number. Don't be hesitant to ask for someone more knowledgable with their system, if they say "well we need to know the grill's...to be able to order". There's one gal, can't remember her name atm, whom I automatically ask to speak to someone else.
I'll PM this to you as well.
