I believe all the aar and t/a's were built in march and/or April '70. So it was a mid-year offering. When I bought mine, virtually none of the salesmen even knew about the package, they had to look it up in their sales books. I don't think many were built to order, I think there was a production run, and many went into a sales bank. Mine was in a storage yard in Salt Lake City IIRC. There was like 50 of them there, and I just picked the one that had the options I wanted.
