hello all, i have a 1979 Z28 that had the cowl tag removed from it at some point. this lead me to question if it was a genuine Z28. i was able to find the build sheet behind the rear seat and it is still readable. the car looks to be different than what the build sheet says in terms of decals, striping, color; things of that nature. i was hoping i might be able to get the community here to help me understand what decals and stripes the car had. mostly in question is the RPO codes BW1, B81, B89, D88, D92, 53A and 62I (this is an I and not a 1). i was also looking for clarification on the job sequence number coding. i think box number 79 is saying the LW is lower color, UP is upper color, but not sure what ST and W are. either way, i know 11 is supposed to be antique white exterior color as indication by the LW and UP boxes, but unsure of the BK code because i cannot find a color associated with it other than the assumed black. i also cannot find any information on box 105 decals GLD 28 (i assume this is a gold decal of sorts) and box 106 COL JACK TAN 2127. any insight on these items would greatly help me in putting the car back to original. it currently is the original white base coat, but there are no stripes, no decals, no other colors really other than the tan interior. thank you in advance for any help you may be able to provide.
