Have the right tools.
Use the correct coupler for the locomovtive you plan to convert. I’m assuming you’re changing to MTL’s.
Buy the MTL coupler tool kit (around $30) It will provide you with several sample couplers, height gauge, drill, tap, grease em, and instructions.
Set aside a workspace with a good lighting source. A magnifing glass helps. A head mounted one works best for me.
Have fun.
