Service Parts Identification and Options

[Greg Saldaña]

Hey everyone, I was wondering where I could decode all of the options that are in the glove box. I have a 1986 K5 with a 305 and 4 barrel. I will leave a picture of the glove box below. Thanks in advance

Codes are in the parts manuals. Should be able to get them here. Note that codes between cars and trucks were sometimes shared, but were not always the same thing, so best not to use online decoders. Most I'd seen were obviously for cars. G80 comes to mind as one, but I'm sure there are others (Edit: Cars and trucks had G80 codes, but cars were posi/clutch style LSD's, trucks were the Gov-lock)

Should be the proper year parts manual in one of these two links:

Thank you, I’ll give it a look

Just Google rpo codes. There are a few easy decoders that you just type the code in.

Thank you I already got all of them decoded!

Am I missing something?
The codes are interpreted next to the code.
Later models only listed a series of codes and those I have to decode using online truck RPO codes.

On the old style you see the description of the code until it gets cut off. It's typically enough to work with but in some cases a bit of important info may be cut off.
Take C60 above as an example. You can tell it has front AC, but which version? There were three.
C60 AIR CONDITIONER,FRONT,MANUAL CONTROLS
C61 AIR CONDITIONER,FRONT,AUTOMATIC CONTROLS
C62 AIR CONDITIONER,FRONT INSTALLED,FLOOR MOUNTED
