I was just on this site and printed up their RPO code list.

http://www.ls1info.com/1999/general/1999frpo.html

I wanted to see what my RPO codes meant and this list does not have about 10 codes that my parts sticker has.

The codes on my sticker, but not the list are:

DL5
K43
MX0
NF2
STE
VM3
V73
Z28
1SE
1S2
6ZL
7ZL
8TJ
9TJ

Does anyone know of a better RPO code list that will tell me what the RPO codes I listed mean?

 

I had the same issue as you i have about 10 codes i cant find.

However,

Z28- should be obvious
DL5- Decal roadside assistance
MXO- Automatic transmission (merchandising option)
NF2- Federal Emissions requirement, (Tier 1)
STE- ST Therese Canada, manufacturing plant



These are the RPOs i think you may have copied wrong
1S2- ?
1SZ-discounted package, factory built car ( not customer or dealer ordered) also used to denote a end of production run factory stripped car

K43-? K34-cruise control

V73-? U73- Fixed mast atenna

as for the others, i dont know them

Hope that helps

 

Thanks for the info.
