  This part has a part number 8A-10990 the pre-fex is 8A but the part number is still 10990 I have also seen two other temperature sending units with an original box with 01A-10990 with a double Prong sender.

  Domenic,
A very important lesson for anyone attempting a proper restoration is fully realize that service parts were supplied to "service". There was little to zero concern that the part was a "direct and exact" replacement for what was installed upon the assembly line.

I see ads like the one you'd referred to wherein the poster has simply copied what information they found in a parts book.

As far as the basic part number being the same: Ford, in my opinion, has maintained the best parts numbering system of any of the major car manufactures. That basic part number was and is used for years - even decades. That makes it much easier to identify what the part is.
Of course the prefix and suffix often change to indicate design changes and or year / model application.

  Every body who own"s a 1940 Ford with the proper" A" heads knows their is only one port on the driver's side to install a Temp. sending unit. Their is no port on the Pass. side head to install a second temp. sending unit. I believe but could be wrong that starting in 1942 each head had a Temp. sender and when one side of the motor got up to temp. it sent the message over to temp. sending unit two via. a cross over wire, then to the temp. gauge. This is possibly why they needed two terminals on the end of the sender starting in 1942 .
