Yeah, I've had good luck with Rock Auto as well although I do prefer to buy from the local guy especially the local shops that ARE knowledgeable and fortunately I do have one locally.

The reality is, unless they're also on this forum, I doubt you'll find one who's as knowledgeable about our rigs as we are.

Oh and for the OP (theheep) don't forget to read the FAQ post at the top of the forum. Rock Auto is already noted there as a good source for parts.
