About these REDBARNS kits, what is the toy "engine" that you put in ? Do you run KATO engines in these shells ? Will the chassis fit properly or does it need any cutting under the shell where the ends will touch the body ?
I am asking because the shells are a bit different than the KASLO ones.
i use kato sd40-2 mid production. since these units feature some underbody detail molded onto the fuel tank, the shell needs some filing on the inside. not a big thing though. lengthwise they fit perfectly.
