Missing build sheet

[1BAD426GTX]

I am looking for my missing build sheet, RS23J96107360.
I've owned this GTX since '76 and haven't found it anywhere in the car.
It did have 3 other partial sheets from 3 different Satellites.

Hmm,
Good luck with your search
You have looked in all of the possible places (in car) correct?
Above the glove box also?

Thanks for the response.
I've looked under both front bucket seats, behind the front seat backs, under the carpet, on top of the glove box, and found 3 different build sheets under the back seat. None of the three match my car. My hope is that someone has come across it.
