Yes, Ebay is a good route to go, the Rivieras are particularly popular.  You could go to the Riviera Owner's Association website (believe it's ROA.org) they have a magazine and forum where I have sold many Rivi parts successfully.

I would recommend craigs list.  I've sold a few cars there, and it really didnt cost me anything..  You can upload photos and just about everything else.
