Chris,
Your project looks very similar to mine. I favor the Maine Central and they had a few "chopped nose" GP7's. Like you, my project started off using a Red Caboose shell. I contacted my good friend and fellow forum member, Old Goat and had him do the modifications. I also had plans of possibly using a donor Atlas chassis for the running gear keeping the TMCC set-up. Problem with that, is that the chopped nose prevents the use of the front motor. Had thoughts of possibly removing the motor from the truck and using only the rear for power. A bigger problem is the chassis itself. You would think that since Atlas purchased the RC molds and made some detail modifications the bodies would swap. Not! not even close. I will probably wind up using the complete RC chassis and motor and install my ERR Beep Comander board for control. Good luck!
