RPO code list
 

found this service part identification list also known as RPO list if it helps it is a full listing it is found on the trunk lid on most cars

http://www.angelfire.com/ny2/96transam/rpocodes.html

Just FYI, this RPO list is still up, although it seems dated from the early '90s.

So it's not absolutely complete, but it still helped me "fill in the blanks" as to what a lot of the RPOs mean for my Monte. :thumbsup: What can I say, I just like knowing these little things!

:bump:

For example, did you know that Z34 is not an actual RPO code? :wtf:

Anyway, there are still a few codes I haven't found a reference for, like R7A, R9Z, and IP3. Any clues or tips would be appreciated...
