I went into the RPO decoder and typed the RPO #'s in and it gave me a description of all the codes except for E72, UU8, AO1, IT4,. Is there any way I can find out what the desriptions are for these codes or does anyone out there know. Thanks for the info! John

Here's what I could decode:

E72 : BODY LENGTH, INCR I8 INCH

Somehow, I doubt that belongs on a ThirdGen.


There is no "AO1", but there IS an "A01" (with a ZERO instead of the letter "o"):

A01 : WINDOW, TINTED, ALL SHADED, W/S

I couldn't find a "UUB" nor "1T4" code, but the numbers can be difficult to read on the RPO labels due to the odd font. The closest I could find is:

UU8 : RADIO, AM/FM STEREO, SEEK/SCAN, AUTO REV MUSIC


1TA : AXLE, FULL FLOATING

Again, that should probably be an RPO from a truck, not a ThirdGen. I couldn't find anything closely related that would apply, either.

If you study the label a little more closely, you may find some of the numbers appear to be alphabetic characters, and vice versa.

Thanks Vader!
