Hey guys I have looked everywhere for these, on like 10 sites with Rpo decodes and came up with nothing.

Here they are if you possibly know what they stand for.

6Zx
7Zx
E5Z
E6N
NM4
ZG1

Also the paint code I believe is 15, Silver anyone know the WA code?

Thanks for the help.

 

well I have:
- 6ZW - SPRING, COMPUTER SELECTED, FRONT, LEFTHAND
- 7ZW - SPRING, COMPUTER SELECTED, FRONT, RIGHTHAND
so the 6Zx and 7Zx might be the same area but different part (aka a different spring?)

- E6E - SLEEVE, SPEEDOMETER GEAR
E6N might be, again, same part but different gear? What's your stock speedo go up to?

The following I have on my own car: (1984 Trans Am)
- E5Z - SPEEDOMETER ADAPTER (DELETE)

NM4...I have no idea. Only things I have with NM in it at all are:
- 9NM - SPRING, COMPUTER SELECTED, REAR, RIGHTHAND
- BNM : ??? (never did figure that one out)

ZG1...noooo clue. :P

Hope some of that helps.

 

NM4 - EMISSION SYSTEM, NON CLOSED LOOP

6ZX - SPRING, COMPUTER SELECTED, FRONT, LEFTHAND

7ZX - SPRING, COMPUTER SELECTED, FRONT, RIGHTHAND
