Thanks Pat! BMR jst sells the instructions with wheel sets, bearings and axles. The do also sell lego to kadee coupler conversion boxes. I found the kadee selection they used didn't grab the traditional lobster claws well so i upsized them and put them in the BMR mounts. The rest of the parts were bricklink orders except for the wheels, which fortunately I found some suitable donors in a project box.
details in this thread.
