I don't know where you are in Ca, but if in So. Cal. there is a place in Garden Grove called Hillco fasteners that specializes in car stuff. They have all the clips you'll ever need for any car and they are better priced than any auto parts stores. Most items are in labled bulk bins and you buy what you need. It is family run and everyone there is very knowledgable and very helpful. I won't buy hardware, wiring, etc from anywhere else unless Hillco doesn't carry what I need. I've been buying from them for over 16 years
Well, I went to find their website and was surprised to find you can now order online. It used to be just an informative page. Good for them.
