For what it is worth, the "Motorcraft" solid state distributor with a male cap fits on my car with the screen.
IF that is the criteria buyers are looking for on their Panteras details like that should be known in advance?
Not everything out there made for a 351c is going to be directly applicable to a Pantera. It is a very "unique situation". Even how you route the spark plug wires and the type that you use has special application.
