Just to pitch in my two cents worth. As a need for more gauges in the dash due to L28et swap, I went with the approach of filling in the cigarette lighter and hazard switch holes with SEM bumper repair, while sculpting a hole for one smaller 2-1/16" Autometer boost gauge. I used a series one cig lighter had the hazard switch relocated to a newly made aluminum fuse panel cover as well as had a custom bezel made to mimic the dash vents that I am using from a Scion FRS. My dash and center console will be wrapped in alcantara micro suede with french stitching. As such, I needed to have removable bezels for the gauges in order for the alcantara to wrap under into the hole provisions for both the dash and fuse panel cover. My next goal was to create the ignition clam shell gauge pod integrated on smoothly onto the top half with another separate aluminum gauge bezel for an air - fuel meter.
