Yes, would be great if it continued especially to find out if there was a year ('69 or '70) or build date when this factory exercise was implemented. Also, it looks like it wasn't just one factory assembly line that did it because most of the Darts were built on the Windsor plant and the Dusters were pretty much Hamtramck – others? And, sounds like some E-Bodies might have got them – 340's and 440's?So, maybe the guys with E-Bodies could check and post their findings. Wonder if any B-Bodies got them. It all may somehow explain why?
