When the recent MTH pans lean, it is because MTH left out a very important arm that connects the pan arms to the pan base so the pan will not lean. I have had to put these rods in many engines that were missing them. All the MU cars are missing them. On later MTH products, the earlier double contact shoes needed to be installed.
The holes are in both ends of the pan. You just need to make up a piece of wire to connect both ends. Your pan will now stand up straight. It does not need to be fancy.
