Yes, the reorder # is AE-5100. I bought it from a jobber on Ebay. I don't think American Eagle sells direct to consumers.
Search for them under "radiator, aluminum, chevy". Should see several different sellers listing this radiator then just shop for the one with the best "buy it now" price. That's what I did.
Based on what I paid for mine, you can't go wrong.
Haven't installed it yet as it's a part needed for my project, but I see no reason it won't work perfectly. Hope this helps.
