Need help assessing this 1965 Dodge Dart 270 4-dr sedan

Looks like a pretty clean car. Still, look for rust. The VIN looks correct too, as is the way it's attached. No rivets that year. The L is for Dart, the 3 is the 270 body style, and 5 stands for 1965. Looks like they added a coolant overflow bottle, and for some reason they drilled a big hole in the passenger side inner fender, but, other than that, it looks pretty stock. You can find the year and size of the engine by looking at the letter and number code stamped into the vertical surface of the front driver's side of the block just below the head gasket seam. The letter is the year.....A is 1965, B is 1966, etc, up to 1973 when the switch to a number representing the last digit of the year. The next 3 numbers are the engine displacement. If these stampings are too hard to read, you can also see the engine size cast into the driver's side of the block above the starter. The date code when it was cast will be on the passenger side of the block toward the top. Depending on year, there might also be a VIN stamped into a machined pad down by the oil pan seam on the passenger side. '68 and earlier 273's and 318's won't have this stamping. Oh, and one possible reason the radio doesn't work is that the antenna mast is broken off. Could be speaker or cable too, so, not a for sure diagnosis!
