'65 XL convertible. Mine has factory AC with in-dash outlets. Unfortunately, Ford lost all build information (types & numbers produced) for everything prior to 1966.

There were about 8900 XL 'verts made, but no count on how many had the in-dash air, 390 4 bbl. It's rare, but HOW rare?

I also have a '66 standard Galaxie. Both cars are in "rebuild" state (ask my wife and they are junk that keeps her from parking in the garage).

I'll  gove that seat-back thought a try. Might be pretty close. THANKS!
