I need to replace my 501R and 501F built in Subzeros. The units are separated by a cabinet in the middle and they also have a cabinet above them. I was hoping to avoid cabinet reworking right now as we plan on redoing the whole kitchen in 6-8 years. Any suggestions? I saw the Frigidaire Professional and Electrolux options, both of which have trim kits to make them 36inches wide but I am more concerned about the height. I only have 73inches to the edge of the upper cabinets.
