Phantom RPO codes!

[Back N Black]

Ok, so I made a list of all my RPO codes and their descriptions. I have found several codes that do not appear on the GM RPO code list, does anyone know what these are:

MSL
NG5
RSA
UP0
ZGC
1SZ
6GC
7GC

Also, the RPO code L31 is listed as 409 CID V8 (Special High Performance Solid Litter Cam)
I know this can't be right on a 1996 Chevrolet Tahoe with a 350 CID V8! LoL! What's up with that??

A mix of info from various GM documents I have.


MSL Built at GM DE MEXICO SILAO,MEXICO PLANT I believe.

NG5 REGISTRATION EMISSION, CERTIFICATION, FIFTY STATE (50) FIFTY STATE U.S. EMIS

RSA restraint, front seat, 208, auto, passive.

UP0 RADIO AM/FM STEREO, SEEK/SCAN, AUTO REV MUSIC SEARCH CASS, CD, AUTO TONE, CLOCK, ETR. STEREO,AM/FM W/AUTO REV CASSETTE,CD,AUTO TONE

ZGC, I am not familiar with, perhaps misread?

1SC, is LT trim so keyless entry, Stereo cassette and disc as mentioned above and front leather split bench seat tho that could have been upgraded further to bucket.

6GC means computer selected suspension component for the left side front. Not really much info there.

7GC same for right side.

Not sure where you came up with a 409 cid reference.
