I forgot about this thread. I called GM and they told me only 03-04 models. They said they would look into it to see if there are other issues on 05 models and maybe add it to the list. MS3Z I seen those on ebay but I was a little unsure. My truck is my daily driver and I cant have it out of comission cause of some guages.
BUT I think I found what was making my speedometer go crazy. I changed my radio out and the module I put in to replace the factory radio was going out. I changed it and havent had any problems since.

 

I was a little unsure to but he did an excellent job and it includes a 5 year warranty. I just took mine out and drove it without gauges. There was about a 6 day turnaround time including a 4 day weekend.

 

I have a guy in CT rebuilding my 02 cluster right now - the gear selection and the odometer were "bloacking out". I will through him some feedback if it fixes the issue
