Hello Pat. The ICON Trailer Coupler locks can fit a variety coupler styles. The # DT66GR is a 2" trailer hitch, so I cannot accurately recommend a coupler lock based on this. The ICON locks will fit many styles of coupler such a cast, flat lip, rolled lip or sleeve lock couplers. For example, the ICON Trailer Coupler Lock # AL48DQ will fit cast-style couplers with a 2-5/16" ball.
If you can let me know the style of your coupler, as well as the ball size, I am happy to make a recommendation.
