installing new couplers on n- scale GP- 40

[drkelley70]

I have a N scale GP- 40  #3500  and it needs to have the couplers intalled.  I would like to change from the knuckle couples and go with  a coupler that will work with the magnetic decouples on the track.  Any suggestions.

If this is a Bachmann loco, this is what Micro-Trains recommends if you use their conversion kits:

Bachmann Diesel EMD GP-40 (w/ #9722-1 long shank coupler assy) Use: 1134 (001 33 031)
Bachmann Diesel EMD GP-40 (w/ split 1 pc. draft gear box) Use: 1129 (001 30 013)
Bachmann Diesel EMD GP-40 (w/ diecast draft gear box) Use: 1128 (001 30 012) or 1129 (001 30 013)

The number in parens is MT's new part number, the 11xx is the old one.
