Yes, how very true. Amazing what some well-meaning, but uneducated people will do to important artifacts -- especially old vehicles.
Also, that's why there seems to be some interest in "Preservation" classes at some better truck shows -- what an excellent way to showcase what a truly "Original" truck looks like.
I had a conversation along those lines with a guy at the ATHS National show in Baltimore a couple of weeks ago. He tried to tell me his truck was "Original." It had modern polished aluminum Budd rims and radials, not to mention chrome stacks and rear fenders (oh yeah, don't forget the LED taillights).
Excellent point to just stop, think and document before ripping into things and tearing apart.
Sometimes, "Preservation" is a better route than "Restoration."
