Springs sized for 16x7 openings
A door from that year is almost always a single-layer steel panel, no insulation core, hung on torsion springs sized for a 16x7 or 9x7 opening and original steel rollers running in a track that's never been swapped. That's not a guess about the area generally - it's what 1983-built housing actually carries, and it's what we load the truck for before we leave Stuart.
