Since I was lucky to purchase from the original owner... I have been striping the car down for body and paint. I have yet to come across it. I have found a few interesting lables and tags but no build sheet.

Here is what I found:
The seats were made in March 1971
The engine was made April 22nd 1971
The body was made April 25th or 26th 1971 (federal sticker shows 4-71)
