I just got an autometer carbon fiber boost gauge from a member on nasioc. the gauge was used but it worked and was in good condition when i sold it to me, anyways. i get it from ups today and very flimsy packagin, take it out for inspection and the needle fell off!!!! i heared of this happening before with autometer boost gauges. can anyone tell me how to open up the gauge or tell me what i should do.
