A:AnswerThey are the same model, but with slight changes only in the mounting bar on the back wall and a missing hole for middle, front supporting screw.

A:AnswerOutside width is 29 7/8 inches and outside height is 15 1/2 inches. You'll need an opening of 30 inches wide to accommodate this over the range microwave.
