As said above, in 69 the VIN was stamped on the flange where the bell housing meets. Neat car! I was watching the auction to see where this one would go. It apparently did not meet reserve at $41K on eBay. Since you bought it outside the auction, I would have to assume the actual selling price was in this ballpark. That's the tough part of gauging values based on eBay auctions - a lot of cars like this don't hit reserve, and end up selling outside the auction.
I like to keep a "pulse" of the market because I have a very similar car - except mine is a Garnet Red convetible with black deluxe. Mine lived almost all of its life on the west coast. I am pretty sure that I am the third registered owner, although it traded hands with a few collectors but was not driven before I got it. I've had it for over 20 years. Have two kids starting college in the next five years, so I like to keep an eye on the market just in case.
Enjoy your new ride! Hope you get as much enjoyment driving yours as I get from mine!
