*Our conversion’s based on only one model from a production run, there may be inconsistencies in a model’s production run that require a different coupler or model modifications to achieve the proper coupler height for coupler function.

** Metal Coupler Note: It is not recommended to use a metal coupler directly on a metal surface to avoid the possible electrical crossover or shorting that may cause damage.
