A variation to my original question.

Any idea when the last GTX was built at St. Louis?

I recall seeing a list of accounted for GTX cars a while back. Anyone have info on StL cars regarding build dates and such.

Just interested in where mine fits in.

The bill of sale from the selling dealer looks like the car was delivered to the dealer in early September.
At first glance I thought that was strange but maybe parts shortages or something held it up.
