Given how much of Fairwood's original hardware is still in service, the truck carries what a 1981-era door actually needs, not just current-model parts. That means torsion springs sized for the older wind counts these doors were built with, and drums and end bearings that match older track profiles rather than assuming everything's standard modern gauge.
We also carry safety cable and updated bottom brackets, since a lot of doors from that build year predate the safety hardware that's standard now, even if the door itself still runs fine. Opener-wise, we stock parts for common chain-drive units, but we're honest about the limit here: if a specific board or gear for a genuinely old opener isn't something we stock, that's a special-order part, and we'll tell you the lead time up front rather than promise a same-visit fix we can't back up. Sometimes the right call on a dead 40-year-old opener is a new unit, not a repair.
