Okay I found my RPO codes in the rear compartment on the drivers side, using this link which is supposed to have all codes GM ever had I looked up each one.

http://aplsweb.com/Topics/TopicPix/RPO.pdf

My first question is why would they print a code that didnt match.

D35 Mirror LH Remote CTRL, RH Manual CTRL
is a code that halfway matched, I have a RH mirror manual ctrl, and a RH that if your lucky and adjust it by hand with no control stick or lever.

E5Z Adaptor Speedo-DELETE
E9Z Key Speedo-DELETE
6XU COMPONENT FRT LH COMPUTER SEL SUSP
7XU Component FRT RH Computer SEL SUSP
8NL Component RR LH Computer SEL SUSP
9NL Component RR RH Computer SEL SUSP
These are codes that I just didnt understand what exactly they were.

MD8
Y86
These codes, plus a couple others i didnt write down, came up non-existent, Why would GM no longer have code info, Maybe the source is to blame but it seem to have way more codes than I'd ever wanna know.

 

E5Z - No speedometer cable thimble is installed in the transmission tailshaft. Instead, a vehicle speed sensor is installed in its place. IIRC, that begain on 1990 model year Camaros, and 1985 model year Firebirds.

E9Z - Related to E5Z, no mechanical speedometer.

6XU - Based on the calculated weight of the base vehicle, options, and perhaps wheel scale readings, the rate and free height of the suspension sprign is determing by computation to achieve best weight transfer and ride control. This is for the left front spring.

7XU - Same as above, for the right front spring.

8NL - Same as above, for the left rear spring.

9NL - Same as above, for the right rear spring.

MD8 - Designates the use of the TH700-R4 transmission.

Y86 - Option package, used to designate a model upgrade from "Camaro" to "Camaro RS", including all the standard items included with that model. Other option packages may supercede that and add further options to make the model a "Camaro Z28", but that RPO might still exist on the label of a Z28.
