1970 LS6 Chevelle "Pilot Car"

I would assume someone at the plant wrote "pilot job". It says "It'll need wings too!" This was written on the one buildsheet which was found under the drivers side carpet in 1995. The darker area of the sheet (where the writing is) was on the trans tunnel and the sound deadener and heat darkened this area of the sheet. Also found was a builsheet for an El Camino that was a few units away from mine. I would assume a factory worker wrote the comment and also circled the RPO "LS6" and "Pilot Job"
