I would be grateful if someone could tell me when the squarish non- pressure radiator caps were used, and when Ford went to a pressurized cooling system? Below is an ad I placed (in the forsale forum); I copy and paste it here as I understand these are unobtainium, and I wanted the word to get to those who might not otherwise notice. Also, was there more than one variety of these OEM caps? The ones I have are all the same.
Thanks,

I have several of these nos Ford with the red latex gasket (which should be replaced as they invariably decompose). I have 10 or so. $40 each. To be sure, these are squarish in shape with four ears and have a 78 part number. I believe these appropriate for V8s between the end of exposed radiators to the onset of pressure caps. Paypal or any good money accepted. I will pay the postage.
PS the part number referred to is hard to read on decomposing Ford tags, in other words, there is no number to make these specific to 1937 on the cap itself.
