Smyrna's broader housing spans 1951 to 2004, median around 1978, which covers everything from early postwar garages to double-wide doors on homes built after 2000. Candler-McAfee sits well on the older end of that range at 1963. That matters because a door from the early 1960s was almost always built for a single-car or narrow double opening, hung on side-mounted torsion hardware that nobody manufactures to the original spec anymore. When a spring breaks on one of these, the fix isn't a shelf part - it's a near-match, adapted on site. Owners who call expecting a quick swap because a neighbor in a newer Smyrna subdivision got one sometimes get frustrated when their job takes longer. It's not us being slow; it's the hardware being sixty years old.
