[DeTomaso] The Water Restrictor Plate Below the Thermostat

Guys,
Here is a 180 degree OEM-style 351C thermostat from NAPA auto parts:
https://www.napaonline.com/en/p/MRD197
Note that it’s stated that it is appropriate for both the 351C and 351W. I suppose it would work fine in a Windsor because the hat wouldn’t interfere with anything, but I have verified that this is a Cleveland-specific unit.
Works good, lasts long time—and costs eight bucks.
The original thermostat was 192 degrees (or 195? I can’t remember) and those are available too from various makers, as are 160 degree units which are arguably much too cold.

If that supposition is correct, then potentially either a Windsor or Cleveland thermostat could be blocked from fully opening if the disc in the block was solid. There is a significant amount of vertical travel when the thermostat fully opens and although I never thought about it until now, and don’t have an engine to reference to test the hypothesis, it wouldn’t surprise me if you have hit on yet another disadvantage to modifying the cooling system in this manner.

Guys,
Here is a 180 degree OEM-style 351C thermostat from NAPA auto parts:
[1]https://www.napaonline.com/en/p/MRD197
Note that it's stated that it is appropriate for both the 351C and
351W. I suppose it would work fine in a Windsor because the hat
wouldn't interfere with anything, but I have verified that this is a
Cleveland-specific unit.
Works good, lasts long time--and costs eight bucks.
The original thermostat was 192 degrees (or 195? I can't remember) and
those are available too from various makers, as are 160 degree units
which are arguably much too cold.

The pressed-on `hat' on the Cleveland thermostat adds to its
diameter to partially (not fully) obstruct the orifice in the disc
in the block, but I don't believe it adds significantly to its
height? If that supposition is correct, then potentially either a
