If you're gonna do a scout, there are actually quite a few places to get parts, but local to NC is going to be a bit of a problem for you.
Start out with
www.binderplanet.com for a user forum with lots of info. Also check out the South East Binders Association sub forum of Binder Planet to find Scout owners close to you.
I buy a fair number of used parts from ScoutCo Products,
Scoutco Products but he's much closer to me than you, the owner, Mike is a great guy, too.
Other great sources for parts I use;
Scout Parts! Super Scout Specialists, Inc. Home Page www.ihscout.net
IH Parts America
Isa's International Harvester
IH's are more expensive to build than Jeeps, and Scout 80/800s more so than Scout II's. But they are cheaper to build than EBs and Early FJs...
