model train help...

[Amtrak47]

ok forum friends, I have a couple of questions here please help.

1: I want to add ditch lights to my MBTA f40, how to do I do this? is there a specific tool? (I want the ditch lights circular and not square like on a Kato f40)
2: What are the correct Kadee couplers for Horizon coaches?

Any help would be great

I may have been a model railroader for a while now, however customizing is a whole new world to me

2: What are the correct Kadee couplers for Horizon coaches?

The first and best source for Kadee conversions is the Kadee web site. They say #5, #58, or #454 w/#36.
