Hello-
I have a 1986 IROC and just finished decoding the RPO. However, the decoder didn't know the following codes, and I was hoping some of you out there would know what they were.
1. B26
2. B3W
3. B9K
4. C4B
5. E72
6. GC5
7. GC6
8. NOD, or possibly N0D
9. YT9
10. 1AZ

Thanks in advance,
d

 

1. B26 - ORNAMENTATION, INTR, DR PULL HANDLES, FRT
2. B3W - ADVANCE PRICE SHEET
3. B9K - CLOTH TRIM, PROCESSING OPTION
4. C4B - Don't Know
5. E72 - BODY LENGTH, INCR 18 INCH
6. GC5 - Don't Know
7. GC6 - Don't Know
8. N0D - DUAL EXHAUST
9. YT9 - REINFORCED DOORS
10. 1AZ - MODIFICATION STOCK ORDER OR ORDER SOLD

There's some at least, maybe someone else can tell you the rest.

 

Jason1313-
Thanks for that! I really appreciate it.
Do you know what the B3W, Advance Price Sheet, means?
The car has 4-wheel discs, would that be one of the codes?
Thanks,
d

 

4 wheel disc brakes is code J65.

 

NOD - Assembly Plant,Norwood,Ohio.N10 is the code for dual muffler exhaust on the early 3rd Gens(at least '82-'83 not sure when it was dropped).And then it was the code for the dual cat convertor exhaust of the later cars.

1AZ - Customer Ordered Vehicle
YT9 - Option Package,Fisher Furnished Parts

The other codes not ID'd haven't found yet.And sometimes the cryptic nature of the codes raise more questions than they answer.And GM has a habit of reusing codes over the years(N10 is a good example).Hope this helps.

 

Not sure what the Advance Price Sheet means. Coolram62 pretty much said it, the codes alot times leave more questions than answers. I wish there someplace we could go to get a full explanation for the codes, until then we are stuck with little short explanations that dont' really tell you alot.

 

For #5 . . . E72 . . . could you possibly mean E7Z?

 

Topless-
Yes you're right it could be that... the image I took was pretty fuzzy. If it's E7Z what does that mean?

 

E7Z - Key,Speedometer(Delete)

 

Coolram-
Thanks... what does that mean?
