Shelby Boss 302: questions about history

I enjoyed the pictures and story in the Heasley book RARE FINDS (one of two he has written with
this title, from CarTech in the Midwest) but have a couple misc. questions as I was re-reading the story.
Somewhere it says the quarter panels were replaced by a restorer but I thought (and I have never worked on the sheet metal of a car) a quarter panel was the front 3/4 and rear 3/4 body outer pieces so in a '69 Shelby those would be fiberlgass or do they mean the sheet metal supports underneath? You wouldn't have to worry about the fiberglass rusting.
Also it says the factory employee who first bought the car removed some of the Shelby-like features. Does that mean he removed the Shelby fiberglass front and and rear end body panels? But then the story says he left the Shelby snake emblems on the roof (however I realize lots of Mustang owners put those emblems on their non -Shelby Mustang).

Finally it says Edsel Ford II and Shelby wre wiling to put in writing that the car was built as a Boss Shelby or Shelby Boss but I wonder if the average Joe would have been able to reach people of such stature with such a request (my experience is that people like that hate to sign anything without a phalanx of lawyers in company). He must have been a heavyweight collector!

Overall it is a heartening story that a employee can buy such a one-off car and I bet it has happened at every Detroit automaker.
