yeah, gage manufacturers make adapters for them. Contact Welcome to Street & Peformance , they have all of the ones you'll need if I remember correctly. I used an old Gen3 oil pressure gage and broke the top half off and drilled/tapped for my OBS pressure unit. Water temp adapter from hotrodlane. The last truck I did I tapped the water pump for the water temp sending unit, behind the tensioner in the flat area.
