I think most of what was obliterated chrome tree wise of the XR6 was for the Cinder Bug issue. I believe the two trees in the tool were end to end with each other. So the longer chrome tree for the Cinder Bug encroached on the XR6 tree. The tree for the touring was changed a great deal for the post My Mother the Car release, losing the quad headlights and the cycle wheels and other parts. AMT also tooled up a new front axle and Frontenac head for that tree. The photos below are top to bottom; My Mother the Car, Cinder Bug, and Original 27 T / XR6.
