Thanks for this tip- I called Foley RV and the lady DID know exactly what I needed. She only had one but I ordered it ($31.00 and change, plus shipping) but she gave me the part # and guess what- turns out Camper Clinic in Buda has 2 more on the shelf and I got them too.
By the way, you have to get them from an authorized AS dealer. The 21.5" x 4" (inside measurement) part number is 381551-02.
