OLA Cape Cod

I have a pair of Original Large Advents in need of repair. Woofer surrounds are shot and the fried egg tweeters are disintegrated. My father-in-law bought these new, and I remember them sounding beautiful. I don't have any particular use (or space) for them - any ideas on where I might find someone interested in them for restoration? What sort of value might these have in this condition? I'd hate to break them up and toss them but I need to get them out of my workshop.
