Mark;
I wonder because I don't know for a fact what to install here,a pulley like your good one or a cheek block that would fit the dagger board width .
The reason I inquire is (besides the fact that I don't know)...can the pulley wear a bit to one side and lean over causing friction when it might rub the daggerboard....?just wondering if a cheek block (I believe that is what they are called)could work here...screwed into epoxy filled holes in the board...Jim
