I got a Kato SD70ACe in the mail today and while it is beautifully detailed, when I picked it up out of the box the trucks fell off and the little drive rods attached to the worm gears came with. Does anyone know how to fix this? I tried putting the trucks back on, but they won't stay. Are they supposed to click or snap or something? I don't want to put too much pressure on it because I am afraid of further destroying it. Can someone please help me?
