I got mine from Vintage Trailer Supply.
These guys are very courteous and professional. Their prices are extremely reasonable as well.
I called them several times, in my earlier years of restoration, and asked lots of questions about various things.
Excellent people and fast shipping too.

Caution , on some models the top clips are not the same as the bottom , check what you have . The camping stores only carry one style . We ordered ours from an AS dealer , 31 cents each , get a few extra . Good luck
