1990 zr1#68 supplemental material

[Sledgehammer54]

Hi
Lifelong vette owner but this is my first C4 Zr1 it?s a 1990 number
68. I inquired at the bowling green museum about acquiring the sticker
and build sheet for the car but was informed there was also supplemental
material that the clerk had not seen before. Another clerk referred to it
as a ?trip car?. Gm was the original purchaser of the car and believe it was sent back to Michigan for testing or shipping out. Any info would be greatly appreciated. Im attaching all the paperwork and a current pic of this awesome car.

Thank you.
