Scott,
I have not had that kind of luck with NAPA around here (BC) or Washington State. They can't even find stuff in the books let alone order it. I find it very convenient to use Jim Carter. At least I know they have it.
I remember when I lived in Lexington, KY there was a parts store that would have any part just about by 5 if you went before noon. I think it was called Eastland Auto Parts.
