Rear mount for cabinets

Thanks for posting. I am afraid we don't have an exact match for this bracket, but our 32-119 pair might work as a substitute, so long as the size of the gap that accepts the track is comparable. See the dimensions below. Unfortunately none of these replacement sockets have plugs like your old ones do; instead they mount with fasteners to the back of the cabinet, so you would have to drill holes to do this. Let me know if you have further questions.
