A home owner from Brownstown, Michigan says:

I have Merillat cabinets built between 1988-1989. The track socket is plastic and it has broken in two of my cabinets. The piece is still mounted to the back but the side piece of it that the rail slides in has snapped off.

I have Merillat cabinets at home and have had success with our 32-012. Now, without knowing the size of your sockets or seeing what they look like, I am not sure that this will work, but look it over and see what you think.
