Hi Pete. Check out Elgin Industries products (http://www.elginind.com). They make parts for the OEM's and they offer a replacement pitman arm for your Nova. Part number 3K6150 for manual steering. The one I have is definitely a nice piece (forged) and the box states it was manufactured in the USA (no Chineseium...L-O-L)

Hope this helps.

And btw: as near as I can tell that original power steering box and pitman arm you bought from me was never molested and I'm confident the numbers are right.
