Could someone run this VIN and post the results?

Edit: JT has scanned it for me!

The site says it has a full build sheet, it's just hidden behind a membership fee

 

Don't put too much into the definitions as Compnine uses a universal/generic definition per RPO code and GM changed RPO code definitions over the years. The RPO code itself is the important info.

Thank you!

 

FWIW, here are some of the missing RPO's that I found:

6ZX - SPRING, COMPUTER SELECTED, FRONT, LEFT HAND

7ZX - SPRING, COMPUTER SELECTED, FRONT, RIGHT HAND

9NL - SPRING, COMPUTER SELECTED, REAR, RIGHT HAND

(No Rear, Left Hand??)

QDZ - TIRE ALL, P245/50VR16/N BL R/PE ST TL HW4

V73 - ANTENNA, FIXED

 

Ahhh, no wonder my car squats so low... I only have 1 spring in the rear!!

Jk, I'm thinking the code 8NL is the rear left, likely part of the "upgraded" iroc suspension package. The fixed antenna is odd tho, considering I also have U75 (power antenna).

Also, I'm a little confused. J65, G80, GU5, KC4... But no G92? I thought you needed the G92 code to get a combination of all of those?

 

IIRC 8NL would be the Left Spring...

 

What you have to remember is that a code only needs to be there to differentiate combinations of parts. Look at the 87 drivetrain chart in the tech data. Notice that G92 was only optional on certain engine/trans combos. The key word is optional. If there was a choice (Option) between two ratios, the "performance ratio" of the two would have G92 on the SPID. When an engine/trans combo only had one available gear ratio, G92 wouldn't apply because it was standard, not optional.

Edit: Z49 MANDATORY CANADIAN BASE EQUIPMENT MODIFICATIONS(CANADIAN) CANADIAN(Z49) might have something to do with it too... Export cars frequently had to have certain substituted equipment. If all logical explanations don't add up, being an export is likely the culprit.
