Looking for a coolant sensor adaptor that screws into the passenger side head of my 5.3. Want to use my 95 GMC Sierras coolant temp gauge and need that adaptor. The size is a 12mm x 3/8" pipe. Been through Street & Performance, but theirs is too long. Can't get my sensor into it because of the length. They sent me a short one, but the threads in it were different and couldn't screw in my sensor. I'm thinking of just using their long one and putting on a brass elbow. It'll look odd, but I think it would work. Rather have an adaptor thats short though. Does anybody know where to find the one I need?
