I installed my Isspro gages in a 3 pod windshield. How the hell do you get these to be flush ?I ground 1/4" off like the instruction say to but once all the gages are in stalled I cannot get it flush. I can see light on the top where the plastic meets the headliner. I have light all the round the gages. It looks terrible and yes I took off 3/8" off the mounting screws off of each gage so there is no interference. It is very tight to say the least. Anybody have any pointers with this type of install with Isspro gages. Thanks
