K7 CPR SD30c KIT
This kit is intended for the experienced modeller. It contains a new rear section with 2 choices of fans, a new dynamic brake piece, safety cab, battery boxes, nose, Canadian steps, end pilots, anti-climber, front and rear plows, ditch lights front & back, roof antenna, horn. I based the pieces on an Athearn SD40-2 engine. It probable will work with other engines but I have not tried them.
