I currently have a 27" drop in range that is almost 20 years old. I would like to replace it with a 30" free standing model. However, the "Spacesaver" model has my two adjacent cabinets 3" too close to each other. Since the drop in is hard wired, I know I will have to put in a four prong outlet. I am not an elctrician, but is this something I can do without calling in the pros? Once I get the drop in out, can I just unscrew the cabinet (the one on the right) from the back, move it over three inches and reattach into the same stud holes? In addition the countertop will have to be cut out of the back and the kick board out from below. How is the coutertop attached to the wall? Can this be done as a first time DIY job? Lots of questions, but any advice is appreciated.
