This locomotive fits over a LifeLike GP 18.A bit of filing might be needed for making the motor fit the body.
Side frames have to be removed from the body shell and attached to the donor
mechanism (a Life Like GP 18 - the older version with the plastic frame -
NOT the newer metal split frame version).
The donor's bogie side frames filed flat and super gluing the 3D frames on.
