According to the parts xref these are modern thermostats that will fit that you may be able to find over there. If the links will work, they cross to current Napa numbers:napaonline.com/en/p/MRDPM1800025?interchange=1napaonline.com/en/p/MRD70?interchange=1
Different temperatures and both have a flange diameter of a little over 2.1 inches.
Be careful on the new radiator caps. Packard until 1955 used what is called a long reach cap. If the radiator is still original type, the sealing surface in the radiator opening is lower down than modern radiators so the spring and rubber sealing washer on the cap that goes against the surface needs to be longer. I don't remember the exact difference to a modern cap but believe it is something like 1/2 inch. The shorter spring standard reach caps will not be able to seal.
