""The wheelbase of the F-Series short wheel base pickup was shortened and inner and outer panel of the pickup box were shortened to meet up with the F-Series doors. We had an idea that just short-stamping the box inner and outer would let us marry the rear pieces to the B-Pillar. Not so fast, there was a 1/10th of an inch mismatch between the panels because of the sweep of the bodyside contour line. So, this idea was not feasible for production, but was OK for a prototype for proof of concept. To make the fiberglass rear roof, we stripped the top off of a Chevrolet Blazer and mated it to the top of the Ford pickup box. This roof retained the liftgate from the Blazer. The idea for the front of the roof was to have a pseudo Targa-style roof contour that swept across the roof. That this over-the-roof contour could be construed as a roll-bar was a great aggravation to Ford’s counsels, so the prototype did not have this design feature.""
