I saw a 59 on their lot this past summer when I passed by there to/from the beach. It wasn't in the best of shape but I've seen worse. Part time guy told me that he din't think the owner would part out the car but you never know. Might be worth a call. If so, definitely ask for close up pictures before you buy.
I don't know if they still have the car but there is a picture of it on their website.
