I'm sure this is posted somewhere but I couldn't find it.

Is there a master list of definitions?

Do all the years use the same the codes?

thanks,

This is generally considered a 'complete' RPO list for C4's. I have never checked it and I use a different RPO check that I have.

The mess in that other link is just that 'a mess'. There is maybe one here on the CF but I've never looked because I don't use it.

On a side note, if the sticker is missing, is there any other way to find the RPO codes for your C4?

What year and where are you looking?

If it's a '90 or newer just take the VIN to a GM parts dept and they can do it for you.

1985. The sticker on the rear storage compartment was obviously ruined and peeled off by one of the previous owners. The more I work on this car, the more I hate the previous owners.

I had the same problem, also a 1985. Here's the kicker, to get a "real" replacement of the SPID, you need a good picture of the old one. Seriously. The information from the build sheet will have all the codes, but it will not get you a replacement SPID.

Excellent, thank you. Looks like it's $45 now.
