Reply to "Five modifications NOT to do to your Pantera"

I'm weighing in a bit late but being one of the biggest modifiers among the group, thought I'd put forth some possible improvements of the older and larger among us. Would headroom improving dropped floor pans or passenger leg room improving bulkhead reduction kit be considered mark detouring changes? Or would such changes be considered age related girth improving positive mods. We simply do not look the same in the mirror these days. If our beloved Pantera cars could see, I wonder what they would see after 40m years of automobile life.
