Somehow I missed this build completely until now. It's obvious this one is going to be nice! The bracing removed from the trunk area made me feel much more comfortable with a rear impact. The interior framework was going to start collapsing almost immediately with the initial impact. The body should strengthen the c-notch area when it is bolted down to the frame. If the body is shimmed where there is no pulling force at each bolt when pulled tight, supporting the body/frame at each end of the frame should make no difference in door gap. Roger has the right idea of adjusting door gap by shimming where needed. Wescott recommends this with his bodies. Henry's bodies react well to shimming also. Just my opinion. Very nice build Roger.
