search for something like "cc knobs" or "climate control knobs" on here. i thought i had the thread bookmarked, but i guess not. its a long thread...probably 10+ pages so youll know its the one when you see it.
anyway, you will not be able to find a pair of the polished knobs. i can recall a handful of times i've seen some for sale since they were almost-new back a few years ago. i snagged the last 2 (98-00 4 cylinder) pairs garrett on v6p had and one pair was for another member on here.
just sold mine last year. your best bet will be to locate the thread in a search, and go for the TL knobs. i was going to, then decided not to waste any more money on this car.
edit: the acura part number is in that thread, also.
