Well, I am by no means any guru but I'll try to help. I restored my 63 back in the mid '80's so I'm kind of out of date on prices and plus mine is a convertible and I'm guessing you're talking about hardtop quarter panels? Try this site and post a question under the early generation threads. Somebody on there should help:

Otherwise try
www.nnnova.com and then look up the phone number and ask for Wayne Bushey. He'd probably know and he may just buy it??
Mystery, BTW Got to love those black cars. Cool but hard to keep clean. Nice car!
