i have 68'b body with 440, non ralley dash, i am wanting to keep the factory temp gauge working in the cluster and i am putting aftermarket temp guage under the dash, my question is, i do not have 2 outlets on my water pump for another sensor i wld have to take off the pump and drill another sensor hole, i want to hook the factory gauge and the new temp gauge on the same sensor, i have not been able to crank the car to test it yet, putting new dist. in, i was wondering if anybody is doing this? will it work?
