Source for '72 Chvy Truck Parts?

Hi,

I've just bought a '72 Custom C10. It will be my daily driver while I fix-up my battered '71 Ragtop Vette. Owning the Vette has spoiled me in at least one sense: I can buy any part on her via the various Vette parts houses. Will I be able to do the same thing with the C10, or should I plan on making regular trips to the local "Pull-A-Part"?

For example, my first two projects:

1. Door locks don't work. Probably have to replace locks, possibly internal mechanisms.

1. Driver's door missing window crank handle (although the mechanism works)

Thanks for the help.
