A full replacement means pulling the old door, track, and springs, inspecting the jamb for square, then setting new track and hardware sized to the new panel's actual weight - not the old door's weight, which is the mistake that causes most of the early failures we get called back for. Spring selection is the part that can't be eyeballed; it has to match the finished door, insulated or not.
Given this area's climate classification and its mostly 1960s-vintage housing, we size springs and weatherstripping to the door being installed, not a generic default. We don't install oversized custom openings without confirming jamb condition first - on a house this age, skipping that step is how you end up paying for the same job twice.
