This was NOT the case with the original Ahm/Pola/Atlas boxcars and reefers of the 1970. Also the die cast truck is offset attached- NOT at the bolster as was o scale cars and the pola/ahm/atlas plastic cars the time were.
Those Lionel early (full) die cast trucks could not be attached to a full o scale bolster without obtaining the high water pants look!
I too noticed the "funky" offset of the truck kingpin(?) attachment to the floor, but just figured it was part of making/adapting an "el cheapo" car with what ever left over parts you had. But obviously this was the real deal and a deliberate designa change to make the trucks work.
