I'm looking for the bed and windshield trim for a '65 Ranchero.

 

You can use the bed trim from any year Ranchero, 60 to 65, they are all the same, though some are stainless and some are painted. The windshield trim is the same for all 60 to 65 Falcons and Comets, with the exception of the 63 to 65 convertibles and 2 door hardtops (Sprints and Futuras).
Hope this helps.
