It's been some time but I did see those in the Newark catalog, however right now I do not even know if they're still in business. If not, seems to me that WW Grainger should have what you need. Perhaps even Digikey. If you use Google to find Digikey, make sure you go to the one that is one word, not Digi-Key. I have no idea who those people are, the one you want is one word Digikey. Their website is actually pretty good, at least you can get the price before going to checkout like some places.
