Found this on G35 driver. Now lets scower the other Infiniti Nissan forums for DIY's and try to compile enough info to give it a shot, the clusters and command center clusters are fairly cheap on EBAY I am going to give it a shot if it works great if not keep on trying until I get it right or cost to much to continue or find a 08+ to see if that works, my plan B is to get a 07+ G35 cluster and dissect it to try to transplant those led's and covers over to the M cluster wish me luck.
D.I.Y. 05-07 Gauge Cluster Disassembly
Couldn't post in DIY section.
First off,
***I am not responsible if you eff up your car. Undertake this DIY at your own risk. I've done this before and know what I'm doing, you may not. Please read all steps before starting anything. If you find anything you are not able to do, do NOT do this DIY.This was your warning!!!!!***
Now on to the DIY.
There are a few diy's already for removing the cluster so I will skip that part
Cluster Removal
That is for an 03-04, should be the same roughly, I have an 04 so if someone with an 05-07 could chime in and let me know if this is the same for those years that would be awesome.
First we have our lovely cluster, in this case we have a 2006 cluster for a 6MT. I have already taken this cluster apart prior to the DIY pictures, wanted to focus on taking it apart rather than pics are first.
So lovely, first thing you will notice, is the 8 clips (4 bottom, 1 each side and 2 top) These need to be gently pulled out and the glass lid pulled off. We now have this.
THIS IS THE HARDEST PART OF TAKING IT APART!!!!!
Get 2 spoons from kitchen, ignore questions about why from mother, father, sister, girlfriend boyfriend, etc. about why you need them, you just do. We have to remove the needles for the gauges, take the 2 spoons and use them as small pry bars on either side of the needle like so.
Be sure to apply even pressure to both sides of the needle. It will pop off with a SMALL amount of force. Now you just have to lightly (this is a common trend, be gentle with this whole thing) pull on the gauge faces, any screens (odometer and if an AT, the display for that) Will need a little bit of wiggling to get out. Now you have this.
This white part is only held in with 4 screws (the 03-04 gauges had 7 or 8) These 2...
and then 2 of the other side, same spots, can't miss them.
Now you are left with this lovely view
Simply place hand over the front of the PCB (Printed circuit board) and tilt cluster upside down to remove. Now you have a fully disassembled gauge cluster.
From here you can do a few things.

Repair of some sort
etc.
Hope you all found this as informative as I meant it to be.
