Gary, Welcome to Stovebolt.com
Having a project with your grandson sounds like a great thing. Hope it goes well.
As far as parts you may need, Post them in the Swap Meet here, and someone can likely fill your need. You'll need 4 or 5 total posts to be able to use the Private Message feature here (the little envelope icon at the top right of the page.) That's the best way to communicate with other members on parts deals.
