Thinking of buying a '67 Valiant 100

I'm thinking of buying this '67 Valiant 100 as a winter project to keep myself and my friend busy over the long winter. It's priced good, about 4 hours from me and apparently has good floors, torsion bar mounts, rockers, etc. Complete car, stored 20 years in a barn. Rusty lower quarters and fenders. /6 car, V100, radio delete.

What do you think? Is this car hard to find parts for? How many were made, any idea?
