Fuel Sending unit

I looked up a fuel sending unit for my 65 and what came up is totally different than what I pulled from my gas tank.

Which one is correct?

Here is mine.


Here is what is listed for my car.
Fuel Sending Unit 3/8" 1963-76 A-Body



This one is more like mine but is listed for a B Body.
