Good morning to you all and Happy Easter
Did some more research and came up with the answer. On my Sonoma I discovered there is a Service Parts Identification sticker that was located in the glove box. Taking the General Motors regular Production Options (RPO) codes you then need to do a search on line for the Code Description which after printing it out is well over 50 pages long. You then take each code and cross reference to what is listed as an example on my sticker the code GU6 is listed and after cross referencing I discover I have a Axle Rear 3.42 ratio.
The cross reference list I found was called Halderman.
I now have a complete list of what options were built into the Sonoma.
There were however some codes I could not find any cross references such as K18, NF7, RSA, R6C, R6D, R7B, R7K, R7M, XCE, YCE, YD5, Z31, 1SB, 6AA &7AA.
