got the overlays, and installed it last night. Was pretty easy, but my temp was all messed up, was showing 1/4 instead of 1/2, so i assumed that it was cuz i must have adjusted while placing the overlay. Anyways, i tried re-adjusting the temp gauge by removing the needle and adjusting. After like the 15th try, the spring inside broke. Now my temp gauge does not work at all.
I personally dont recommend installing the overlays, seems very easy but you might screw-up big time like me!
