Just a question that doesn't appear in the manuals...I had my heater removed from my GT (1970), and in putting it back in, it looked like the repair manual shows the heat control valve going to the lower heater core tube. I installed the metal OGTS plate, and it's great. I have an electric choke Weber so that eliminates all that extra plumbing. Question is, does the heater hose that runs from the water pump run directly to the upper heater hose tube, and then the lower with the valve run to the nipple on the thermostat housing, or vise versa? It also looks like the hose coming straight back from the thermostat housing must run all the way back around behind the carb, and then down..or can it be shaped like an S to run in front of the carb, then down? Thanks for your help.
