They fit perfectly in the hole where the MTH truck fits. If you want to use the Lionel trucks, or Atlas O for that matter, I use a piece of Plastruct on the opposite side of the floor on the MTH cars, cut to about 3/4 x 3/4", CA glue it in place (on opposite side), then use a #4 x 1/2" screw from the bottom side and attach the trucks. Lowers the car, looks so much better, and gives it a perfect ride height for adding Kadee couplers.
It is a pain, but it's what you have to do.
