First time ice ever seen one of these. It’s a little chin pad from an under dash A/C plenum that was in a 68 Barracuda. I’m assuming because the 68 cars had a lower dash pad, and the A/C cars needed to match that in some way? But I’ve never seen one, and I’m not too versed in the 68 models, having never owned one. Can anybody shed some light on this that may know something about them? Thanks people.
