take this with a grain of salt, as this is my experience with an A-body reproduction dash pad bought from classic industries for a 73 dart sport.
it looked good out of the box, but fit horrible !
all kinds of tweeking, twisting, clamping and cussing later, and it looked "acceptable" to the guy that owned the car, but i didn't like it.
i don't know who makes these for classic, [nor if it even applies to their B-body pads] but it was a steel frame pad.
just my experience, nothing more implied.
your mileage will vary.
