How unusual is a second build sheet?

[pritch]

I was doing a little more cleaning on my new '68, and I found a second build sheet. I can't imagine how it survived-it was just lying on the floorboard (in pieces) under some dirt and debris between the gas tank and the back of the seat.

Here are both of them. I have them under a sheet of glass to flatten them out. Maybe I can cut and paste and make one complete



And then I noticed the date on it. Tomorrow is my truck's 43rd Birthday!



This is the present I got her. New ball joints, bearings and shocks.
