I have a 70 SS and recently found my build sheet during replacement of my carpeting. I removed the backseat and found the buildsheet attached VIA the hogties inside the back of the seat. I was a very happy camper!!

My question is, what is the proper way to preserve a buildsheet while maintaining the value???

It is in pretty good shape but is beginning to come apart in some places. It has the usual rust colored holes in it.

Do I laminate it or just insert in between a plastic sheet?

Any help is appreciated, thanks Stein...

If you put it in a sheet protector, make sure it is archival quality with no acids in the production process. Must are...

I'd suggest not laminating. Place it on top of a piece of 8.5x11 card stock or other heavy paper, and slide it into a sheet protector.
