This is not my wagon but it is very similar to one I own.
It is a Classic Custom (mid-level trim) six passenger 196/3-speed with OD wagon. It has been off the road for about 10 years I think. Supposedly the OD trans was added by a previous owner. It is available here in the Bay Area for $300 with a clean title. It is complete and has good glass. There is no rust to speak of, based on my inspection of the car last summer. It recently changed hands and the new owner will sell it since he got it cheap but he will not sell parts. I can put you in touch with the owner or you can find it listed on craigslist.com.
Is it from the CA desert area somewhere? Open rear drive conversion? Silver, red interior? If so it's someone I met when I first moved down here in 1996. Can't recall his name.
I remember this because he was having problems with the modified traction bars used to locate the rear, were cracking. I realized the next day what the problem was (torsional rotation: the bushings used only allowed for rear up-and-down motion, not one wheel lifting.) Easy fix. Couldn't contact him to tell.
Personally, I like the 61/62 body style better than the 63 ("car of the year") styling (sorry Tom Jennings).
