Does anyone have experience using precision gages in instrument clusters in lieu of the older technology. In particular the oil pressure and temperature gages would be nice to have numerical readings. Both my sons 69 Mach 1 have oil pressure, temp, alternator, fuel gage, and speedometer. I’m also interested in doing a conversion for my 68 Fastback. I’ve seen some listings for replacement gages across the board but was not sure about quality. I would prefer not to add other gages hanging from dash or some other place in the interior. Maybe someone can share their thoughts or ideas?
