Some of the prices of NOS parts that sell on Ebay are amazing!

How about 500 bucks for 57-73 radiator cap:

I happen to recently buy a repop one for 25 bucks, it is made in the USA, and it has all the same markings on it, but on mine I can tell the markings were engraved and the original was stamped.

Here is another one … 300 bucks for trunk weather stripping:

And in some cases used parts too … how about 4500 for a 1970 ram air III carb:

If you hear of a dealership going out of business, buy up their parts!
