I don't know if I'll get a good answer, but our kitchen has a 27" drop-in range made by GE probably in 1965. They still make a 27" drop-in that is changed in design and features, but basically sounds like the same animal.
What are the chances that I can buy a new one and simply drop it in where the existing range is without renovation? I've asked people who sell them, and GE, and no definitive answer. We want a new stove, but don't really want to make any but the most minor alterations to get one.
