on the RPM and speed meter, can I move the needle up to slide my guages in? because it is sitting at the needle stopper. Don't want to mess up the needle.. Thank you guyss..

 

You can move it up, as long as you don't pull it away from the gauge.

 

There isn't a problem if you gently move the needle. Then you need to slide the hole in the gauge down the needle and then push it below the needle (The part that is attached to the needle) and you can get it around the small edge of the other end of the needle. I did this no problems...yesterday I put in an aluminum gauge bezel and it took me 15 minutes.
