While searching for my paint codes I stumbled on this. I looked up a few of mine, not all. Maybe it will help.

Z06 = Interior, Luxury
Z15 = Sport Equipment , Special SS pkg
Be aware, many rpo's get used for other purposes and do not necessarily mean the same thing in other years and other makes and models. So a rpo list from 2010 might not relate to a car built in 1980.
For instance, G80 limited slip differential. In trucks (not an El Camino though), G80 is a locking differential. Also, Z15 was on my build sheet for my 2002 Firebird Trans Am. To get an accurate description of what the RPO is get a list that covers the year in question.
