Mounted a 2-1/16" phantom gauge in the blank in the overhead console. Think it will look good once I put the angle adapters behind it. As for the sending unit, I cut the transmission cooling hose just before the radiator tank and put a 3/8" brass tee with 3/8 barb fittings for the lines and put the 1/8 to 3/8 adapter in the middle tee opening and placed the sending unit in there. One thing to remember is that this unit needs to be grounded, so a wire on the outside of the tee and a hoseclamp to hold it on the tee with the other end to a ring terminal to the chassis.
