Hey,Just thought I would post my findings for this. Much thanks to CODE4 for the original Motorad PN.Motorad makes the Valucraft thermostats at Autozone. Right now you can only order a Motorad online, and with shipping its around 14-18 dollars.Autozone can get this part anywhere from 3 hours to 12 hours, only it is branded as a Valucraft.Valucraft PN is 17208 for the 180 degree thermostat.Laters!
