99 Passat floor mats

I need help locating the little circular caps that hold down floor mats. I have a 99 Passat with tan interior, and have looked everywhere for these. I checked with the dealer and they said they discontinued that particulat model, and the newer ones do not fit. Any help is appreciated.

You might try www.drewparts.com - I don't know if they'll have them or not but they've been a pretty good source for these kinds of things in the past.
