KF4RCA, your reference to Sears pre-fabricated houses reminded me of my brother-in-law who worked as a "sledger" during summers in high school for a construction company building pre-fab houses. They would put up three wall panels to a room. Then they would put up the last wall panel. If it didn't fit, the sledgers were called in to persuade the fourth corner to come together.
