Funny what you find stuffed in trucks right! So now that you have the gauge cluster out and on the bench, start by taking off the small hex head screws around the perimeter of the cluster.
Once you have that undone, you can lift off the actual gauges from the face and set it aside. Try not to touch the gauges but spend some time cleaning them off, getting all the dust off. I also took off the green metal backing and cleaned that up too.
Now take the new gauge cluster and lay it face down. Take the new gauge face cluster plastic and don't get your prints over it. Lay it down on the cluster and make sure it slots in straight. After you have that in, take the green metal backing and lay it on top.
