i decoded all of my option codes of my '85 Z, and i have a couple that didnt turn up.... here goes...
B3W
B9K
D6J
GC5
GC6
YT9
1AY
72I
82P
Beware that, as most of u know, sometimes the numbers look like letter and vise versa..i did though double check to make sure they were 'correct' to my RPO tag...
if it helps my vin is 1G1FP87H4FL458933

 

I've managed to download a bunch of codes from RPO decoder sites and save them on my hard drive.. I had some of your codes in the list...

( Don't ask me what an advanced price sheet is, or what they mean by "reapply to RR doors" )

B3W - ADVANCED PRICE SHEET
B9K - ORNAMENTATION, B/S MLDG, REAPPLY TO RR DOORS ONLY
D6J - GEAR SPEEDO DRIVEN
GC5 - ??
GC6 - ??
YT9 - OPTION PACKAGE, FISHER FURNISHED PARTS ...
1AY - CUSTOMER/(DEALER) CUSTOM ORDER
72I - INTERIOR TRIM, DK CARMINE
82P - ?? (This is another trim RPO)

 

82P - Wheel Color, Midnight Sand Gray Metallic

 

I know that in '92 the RPO codes that started with G had to do with your rear axle. However i just checked camarosource for 85 and those RPO's didnt show up... so i have no clue what they are...

 

sweet, thanks, if anybody finds out that the "G" codes are let me know..not that its important but ya know...it'd be cool to find out anyways.

 

I can't find the codes on my '92. This is a one owner car that is very tight so no changed panels or parts. Heck I still have the factory radiator hoses and clips, tags , etc. but no codes. I looked under center arm rest and rear glove box. I do have the original invoice but can't remember if they would be on there. Where do I look on the car.

 

Look in the glove compartment in the hatch...

 

I cannot seem to find rpo code 1AY or 1AZ on my '91 Z28.

should it be listed? If so..where?

I know the 1AY is dealer ordered and 1AZ is customer orderd.

Thanks,

 

I did that. No luck.
