I've ordered from most of all the large distributors even from zip-products, I've never been disappoint with them.  They are really knowledgable and the shiping was always fast.  Whichever you decide on, I don't think you'll be disappointed with Zip

Then no matter what part you want the key is to call and ask some questions before you buy.  That will lessen the possibility of getting something you are not happy with.  Thanks Aaron for the list of parts suppliers.  Maybe I'll start by requesting a catalog from each of them.

Don't forget about Rik's. I hear alot of guys use them. I requested a catalog from them recently. They are a new supporting vendor for this site.

I just received my Rik's catalog.  It seems to be inclusive.  Pricing is somewhere at to top end of the catalogs I have Corvette Specialties, Corvette World, Eckler, Willcox, Zip. 

I ordered a couple of dash vents from Willcox.  I messed the order up and actually only ordered 1ea.  When I got it I ordered the second one and explained on the order that I had made the mistake and could they do something with the shipping.  They sent the second one free.  By the way they were half the price of Eckler and Corvette world for the item.  That is not the case all of the time but it was on special. 

I keep a spread sheet listing all of the parts I need or want to replace so I have a record of money spent and to compare cost of the different vendors.
