Gondola's

Hi all. Some time ago, I downloaded the RW Thrall 52'6 Gondola pack 1 and pack 2 re-skin kits. The read me file says "This package requires the The gondola_52-6_mt.GeoPcDx file from either the default or NS gondola downloads available at http://www.stephan-michael.de/railsim/". Perhaps I am just missing something but, does this mean that I have a default gondola? I have one in the game listed as a "Hopper Low Side Gondola" with NS on the side, but I cannot find it anywhere in the assets directory and I don't even know if I am chasing the right file. I also looked on the above website and cannon find the right rolling stock on there either. If someone has some insight, would you be willing to share it.
