For a job 16 miles out from Greensboro, we bring what a 2002-era opener swap actually needs rather than guessing on site: standard rail and belt-drive units, mounting hardware sized for the bracket spacing common in that build era, and replacement safety sensor pairs, since those are the part most likely to be original and failing on a house this age. What we don't carry on the truck is a part number for every discontinued board from that exact production year - if your specific chain-drive unit used a proprietary logic board that's been out of production for over a decade, we're not going to chase down a used one; we'll talk through a full opener swap instead, which is usually the faster and more sensible call anyway. That's the honest limit: we fix what's fixable with current stock, and we don't pretend a 20-year-old board is worth sourcing.
