well...if you scroll down the forum you can see the same topic that you decided to talk about.
Yes you remove the black faceplates and unscrew the screws and then slide the guage over the needle....do not remove the needle. Lift up...and slide out through the hole
I had this problem months ago. I bought PCP indiglos but could not get them over the needles! They say it can be done, but I dont believe it. I removed the needles by turning counter clockwise and pulling @ the same time, but before you start search the threads!!!!
