Tech is trying to show you how well the frame is integrated into the overall look of the car. Bob Parmenter posted a picture (I think) several months ago of a Model A sitting on an S10 frame.... it looked strange since the body looked to be "way up on top of the frame" rather than having the frame appearing as natural.

For an old-time look, any view of the S10 frame or suspension will detract from the overal appearance......it will take careful planning to keep from looking like a pinto body on a 4 wheel drive frame.
