I need a line on where to get some of these plastic fasteners that are most likely going to be removed and re-installed a lot. I'm talking about the turn-down fasteners that hold the battery cover on, snap-down plastic fasteners that hold down the radiator cover, or the inner fender "push to release" fasteners, or the ones that hold the plastic cowling on under the nose of the car. These are going to get worn out, and harden over time. So I'd like to have some spares around.

So I found this site:

Yes, there's ebay and amazon, but has anyone actually tracked down reliable links to actual fasteners that everyone can use? Maybe we need a parts catalog or something.
