They are still available new. Use their store locator to find a shop near you. If they don't have one they can order one for you.

If you are looking for the "king Size" American or Heavy Duti, which was a cantilever, I believe those were only made in 1962-1965, and finding one of those would be tough.
I'd sell you mine, but I've put to much love ($) into her.
I looked at two bikes that look like this yesterday. they said 1967, and they wanted $75 a piece for them. as best I could tell they didn't look any bigger than a curvy cruiser, but they're not my interest so I don't know if they came in different sizes and there wasn't a cantilever near them to compare (peddlers mall).
edit: guess I should have added for someone local (Louisville, ky) it's the peddlers mall on the outer loop near shepherdsville rd.
edit edit : well I was back there just now and one has a "made in china" sticker on the head tube, so I guess they're just styled like one from 1967. I don't know.
