I'm convinced the car that you think is a Packard is actually a Standard Vanguard, like this one

The weird van thing is something really exotic - it seems to be based off a Tempo Matador - but I'm not sure

Also the last picture but one is a Mack - I believe I can read it on the top of the radiator.

Btw nice pictures Mopar!
