The Life-Like GP18 locomotive can be modified to accept the DN163K2 board replacement decoder.
The locomotive samples used by Digitrax for this instatllation needed to have the frame engagement clearance slots under the cab on the fireman-side widened about 1mm towards the rear of the locomotive (long hood end).
This can be done with a small file or Dremel type tool, to allow the decoder to properly engage the casting with the power tab on this side.
The engineer-side slots are OK to fit the decoder power pickup tab on this side.
Be sure to check the motor tabs are safely clear of the frame halves after installation, and that the motor is firmly in alignment and the motor frame is secure does not rotate.
Place a piece of Kapton tape up, over and across the loco frame as shown below.
