E5Z,E7Z,E9Z and other RPO???
 

These RPO codes drive me nuts trying to find out what they really are. My car is an 88 Camaro Sport Coupe.I always thought codes ending in Z were deletes, but these bring up "rear door width" and "body length" junk when I try to decode them

------------------
1988 Camaro Sport Coupe305TBI-4spdAOD-2.73open in "bought stock" condition. That'll change if it stays around here much longer

According to the printout I got from GM E5Z is SPEEDO DELETE..whatever the heck that means.

92 Trans Am/WS6/Blue/305/5Speed/T-Tops

These codes are related to the spedometer. E5Z : SPEEDOMETER ADAPTER (DELETE)

E9Z : SPEEDOMETER KEY (DELETE)

I'm not sure about E7Z.

SO what is a "Speedometer Key" ??? WHat does it do? What does it mean if it is deleted?

AND what is a "speedometer adapter" and what does it mean to have it deleted ...

Does this mean I don't have a speedo cable???

My car was built 06/88
Oh yeah, BTW is 06/88 the end or the beginning of the 88 model year??

Thanks in adavnce everyone, even Drew !

Mike,

A model year typically starts around September or October of the previous year and runs thru June or July. That means the first 1988 Camaros came off the assembly line in September, 1987 and were built until June or July, 1988. Yours is probably one of the last 1988 Camaros built.

Lucky for you, in 1988 Camaros were built at only one plant site, Van Nuys. Therefore the sequential part of your VIN (the last six digits) will indicate build number. There were 96,275 Camaros built in 1988. The first 1988 Camaro had sequential number 100001, whereas the last was 196275. Your sequential number should be towards the high end.
