Not recieving much help here I see!
What type of cup holders are you referring to?

I bought a set of Porsche OE cup holders that snap into the side air vents. No install necessary. Inexpensive and high quality. When not in use they fold together for storage. I keep one in each door pocket. (they are L & R)
Sorry no pix, but I can post later if you want.
