I bought a gauge over lay that is aluminum with the chrome trim rings. I tried installign the last night but had no luck at how to get teh clear plastic cover off. I took the guages out and was able to remove the clear and black part from the gauges themself. But looked like it was glued together. Does anybody know how that clear peice come off. It already got me going becuase I could not figure out that part and then installed the gauges back and then my d4 would not come on so had to take them back out and switch the bulb with d1 but fixed that issue.
