sorry to ask again

i asked the same question weeks ago but nobody had this problem, now i wanna know is somebody is having a vibration noise ( like plastic scratching to each other) on the dash board just around the clear plastic that covers the speedometer?
i took a look a that clear plastic in both side and in one side there ir a big gap can you guys take a look at yours and tell me if you see something wrong? you have to look at it in an angle and compare right to left side. I tried to took cff the cover and see if i could fix it but i was not sure how to do it and i took my truck to the dealer they did not do **** and the noise still there. brand new truck and make nosie like a old car lol it is driving me crazy, need some ideas or advices
thanks
