I've got a whole stack of old GMC Parts Manuals to browse through. Well worth the investment if your rebuilding one of these trucks.

Edpruss, I don't really think parts are any harder to find for the 228 or 248 engines. They seem to be quite plentiful up here. The 236 and 256 seem to be scarcer though.
