There has been some discussion of adapting Bachmann knuckle couplers to other manufacturers trucks. This is what I have done.
I drill a hole in the truck tongue right behind the coupler shank and infront of the axle. I then screw in a "small screw eye" that I got at ACE, part number 76454. This is a USAt Arch Bar truck.
Insert the plastic rod into the eye and then attach the coupler to the truck tongue. The plastic rod does rub against the axle, but it doesn't seem to be a problem. If you cut it off between the eye and the axle, the remaining stub may fall out of the eye on a tight curve.

I think that you could insert the eye between the mounting screw and the end of the coupler shank, this would permit you to be able to cut off some of the plastic rod and still keep it in the eye.
