After reading some old posts I've decided to install a after market oil pressure gauge. I've been looking at the factory gauge set and I think I can use the existing plate to install 2 inch aftermarket gauges there. The guages actually seperate from the plate and there are 1 3/4 inch holes in the black plastic dash plate, if they don't fit I think I can make the holes a little bigger. I want these to look neat and professional, I don't like the idea of a bracket mounted on the dash. Has anyone every done this and does anyone know if the aftermarket fuel guages work with the Isuzu sender in the tank. I see they sell one for GM vehicles and one for Ford vehicles.
