I did come up with a method to mount them so they will look almost stock. I also got LEDs to replace the bulbs in the dash indicator lights and they are already mounted on the modified bracket that will hold the gauges. All I need is the gauges, and they quoted three weeks since I will have a couple of them custom built.
The electronic speedometer will be 4-3/8" dia and read 120 mph, instead of the stock 110. The tach, and all others, will be 2-1/16".
