Parts source for AC Delco other than the dealer?

[tommcbride]

Hi everyone,
Thanks for haveing me aboard. This looks like a great and active forum!
I have a 1995 Fullsize 16 passenger G20 van that I have had since new that I use for hauling my kids around (my motorcycles! ) and would like to do a rehose on the engine. ALL heater, bypass and cooling system hoses. I would like to stick with stock AC Delco parts but would rather NOT get porked by a dealer.
Are there any on-line sources for looking up the parts and ordering them at a relative discount?

Thanks everyone for all input, comments, ane expertise!
