That's definitely a 3rd gen b-body cluster. I'm surprised that it fits the e-body dash that well. I've seen e-body dashes in b-bodies before but not the other way around. Most people don't realize that the front unibody on 3rd gen b-bodies and e-bodies are almost identical other than the upper cowl and w/s pillar. I'm using a 72 charger front unibody clip to repair my 70 cuda.
