Walmart. They're in the ladies stockings isle. Mr LS1- please do an intro... folks around here are pretty picky about that sorta thing...
I purchased a more or less complete set of rebuild parts this summer from Patricks in Casa Grande Arizona http://www.patricksantiquecars.com/contact.html I purchased pistons, rings, main and rod bearings (NORS floaters), complete valve train, and some cylinder head studs. He was great to deal with and there where no problems with anything during ***embly. Good luck...
