This fridge fit the dimensions of my old unit and I did not have to make any alterations to the surrounding shelves. It works great so far ( 2 weeks) and has ample room as a secondary fridge/freezer. Reversing the door swing was a bit more complicated than I thought it would be as it also involved unhooking and reattaching the wiring harness for the interior light. Once I checked out a "how to" video on you tube it became clearer as the instructions that came with the fridge omitted a couple of steps.
