Need build sheet opinions

[Johnny Horsepower]

Pulled the front seat out of my survivor 80 Z28 yesterday.
I knew the buildsheet was there because the previous owner pulled a piece out on accident when checking for valuables before shipping me the car.
the sheet is in 3 major pieces, a few key small ones and five or six scraps. I puzzled together most of it and its all there. I usually take these to a document restorer to have them taken care of. I plan on doing the same with this one.
Here is the question.
Normally i have a one or two piece sheet.
After this is restored should i have them try to attach the puzzles back?
I have always been told to avoid lamination so i am looking for suggestions.

thanks in advance.
