Slant 6 parts

Where can I get /6 engine parts like water,fuel pumps. Head bolts , gasket set ect. All the local chain stores like NAPA Oreilleys ect have no listings. For a 73 225. thanks.

What I would do is, whatever store is most convenient to you, go on their web site and look the parts up yourself. Get a running list of part numbers and take them into your local store. I can go look up all the parts you mentioned on the OReilly site right now except maybe head bolts and find them all. My local store, while they don't stock those parts can get them sometimes same day.
