my car has some of the rpo codes from 1969 need help decoding them
door pads=BLUE?(the car is hunter green with a forest green interior)
Those aren't RPO codes! RPO codes don't change from year to year. They are always 3 alphanumeric characters. They are always the same. Air conditioning has been C60 since the beginning of time. G80 has always been positraction and N40 has always been power steering. The only exception is when a particular option hasn't been available for several years and the company decides to reuse it to bring back memories from the past as in LS6 or ZL1.
Those codes on a build sheet are "Broadcast codes". They are for assembly factory floor use to easily identify parts.
