Very nice job. FYI, the Athearn Andrews trucks will fit on the IM kit built cars without modification. I personally like the Athearn trucks better because the equalize and handle rough track better. If you don't like Delrin (engineering plastic) wheels that come with the trucks, you can replace them with IM metal wheels.
I don't know what comes with that kit, but IM plastic trucks work pretty well too if you replace the wheelsets with some with Metal axles.
