I would recommend the 160° thermostats. The temp rating is actually the temp at which they will close, and not when they open. Because the carrier is a relatively low pressure system compared to today's vehicles, you don't want to be hitting the over 200° temp range that a 180° thermostat will reach. I have seen some 180 thermostats not actually open until 240 degrees. Mind you, these are the low quality ones that you got from Cdn tire. Buy some good quality ones form Ford (use a pair of part number RT350) and trim them down with a set of tin snips so they fit.
