need help with the tamiya dragon wagon

i have the 1:35 tamiya dragon wagon kit, and i am stuck and confused on the instructions for the trailer. when joining the upper and lower frames for the M15 trailer, you have to make two metal hinges that connect the two on the rear. if you still have the instructions, its step 30. there are two metal hinges, a steel shaft, and a piece of plastic that make up the complete hinge. thing is, that the steel shaft is too large to fit in the holes of the plastic piece and the metal hinges. any suggestions?

I have built two of them and had no issues. All you do is stagger the metal hinges and put the plastic one on the end. You may have to bore out the hole on the plastic one slightly to get it to fit.
