I have responded to Tom via email but for anyone else wanting the same information:
I checked with parts at Newell. They said they get the headlight and turn signal/parking light as a single part number from Ford. It is from a 1989 or 1990 F-150 pickup. According to PartsTrain.com, the 1987-1991 Ford F-150 used our lights and turn signal/parking lights and they also show it as a complete assembly rather than available by the ‘piece’. Their price is $105 for the headlight and parking light for one side.
