Hey folks, I went through and dissected the RPO codes on my '85 IROC-Z today. There were a few that I couldn't find, and I searched everywhere I could think of. Hopefully one of you RPO junkies knows!

B2G - One site said this was "Components of IROC package". Is that right?

D6J - The only mention I found of this one was on an Oldsmobile site, calling it "42 tooth speedo gear". I couldn't find it anywhere else. Any ideas?

N06 - I saw that some thought this was "Dual Exhaust". I don't believe that's accurate since GM use N10 for that. The surrounding combinations N05, NO8 are calling out special locking fuel cars. What is N06?

Thanks for any and all help. I've exhausted my pee brain looking for these last few :-)

b4z is iroc package. the other rpo codes mean nothing or are not in my camaro white book for some reason.

 

You have the correct info. The B2G is a part of the IROC-Z package. What part it is ???. D6J is a speedo gear and N06 is a remote locking fuel door. How that is on a Camaro is beyond me. They have the pull open fuel doors.

 

I have the B4Z as well, but found conflicting info on the B2G. Some of the codes are pretty odd, but it was only the ones I listed that I couldn't pin down. Scott, agreed. But I saw some threads about N0D on Camaro sites, just couldn't find where it was ever resolved.

NOD is for Norwood, the cars final assembly point.

 

Thanks for the help folks! In a rare moment of brilliance, I remembered that I have the build sheet for the car that matches RPO to Description. Duh!

B2G is "IROC Components (Decals)"
N0D is "Norwood"

Strangely enough, the D6J code is not on there. It is however on the RPO sticker in the glove box. Must be that speedo gear, or some other obscure code that nobody but an assembler would care anything about.
