My regrets you are still having an issue. Hate it when the Mustang has gas. In the old days, that is how you separated the plow horses from the buggy horses...
Okay, so you still have a hot spot.
1. Did you get the restrictor with the large hole, or did you get the restrictor with the tiny hole?
2. If you got the restrictor with the large hole, do you have a photo of the spring side of the thermostat? Do you have the make/model?
Regardless of restrictor type,
3. Did you check your thermostat by filling your your wife's best boiling pot with water, putting the thermostat in it, and watch the thermostat open prior to the water boiling? If you have a meat thermometer you can measure the actual temperature of the thermostat opening.
4. To assure your system is circulating water, have you taken off your radiator cap when the engine is cold, start the engine and confirm the water is circulating? Again, your wifes best meat thermometer can serve to measure water circulation temperature.
You will lose some water, maybe a pint when you do this. Some people like to put cardboard over their radiator to keep the motor hot. But some of them forget to remove the cardboard. Don't forget to remove the cardboard.
5. Once the car is warm, are your heater hoses hot? Do you get hot air in the car?
We'll get this licked, if it costs you every dime you got.
