Denny, I bought mine off Ebay. I don't think American Eagle sells direct, so that's the only option I found. AE may give you a list of retailers who sell their brand if you call them.
I too was impressed with their ISO 900 certification. I was told years ago how difficult it is to get. So, when I saw they were certified, logic told me they had to be legit and a good company. The square footage of their facilities and the number of employees impressed me that they weren't a fly-by-night outfit. I took the plunge.
And Craig, yes I too was impressed with the over-all quality of this rad. The welds look very professional and the billet style filler neck is good looking too. Mine came with a high quality cap and brass petcock as well. Built in tranny cooler at the bottom of the rad. Both times I've sent the company an email asking questions about the rad they have responded quickly with a very thorough answer. Not these quick, one word answers. Very, very polite Customer service reps ansering your questions. I highly reccomend this rad for our AD trucks if you're not that interested in staying original. High quality at a very low price!!
