How much interest is there in 1960-62 Valiant parts?

I have a guy that wants to clear out his stash of parts. Most of what he has are early Valiant parts. Fenders, doors, hoods and grilles. He has some alternators and starters, Slant six blocks and such. NO aluminum stuff. Hubcaps, 13" wheels, maybe some interior bits and pieces.
I told him that I'd help him clear out his yard but that I have no idea of what his stuff is worth. I could use some of his later stuff from a Little Red Express he had but the Valiant stuff is out of my area of knowledge.
Anyone care to put a fair value of this stuff? I plan to haul it all back here in the next few weeks and would prefer to NOT sit on this stuff forever. I usually deal with '67 and later cars.
Thanks, Greg
