zp3 on build sheet

[slimsls6]

first, thank you in advance for your help. i have a monaco orange ls6 that is mostly original. my question is how did they know what color to paint this car? there i no paint code on the car (--) nothing specified on the buildsheets,
no paint codes hand written on build sheet, any ideas?

Are there any numbers typed in the lower left area of the option section of the buildsheet?

As far as the ZP3 code, I know I've seen that before somewhere, but I don't think it has anything to do with the paint code.

no, i don't see any numbers typed in lower left corner that
would be a paint code Rick

I was wrong, ZP3 does designate special paint as seen on the partial buidsheet pictured here.
