for what i understand, the speedo conversion is just a direct replacement. YOu just have to find a later model SC with the 140mph speedo to put it in yours. About the temp gauge, have you tried checking/replacing the coolant temperature sensor? Perhaps its bad or the electrical boot connector has come loose or disconnected. That could be a good start, and its cheap to replace too...only a few bucks at your local parts store.
