1954 framing predates brackets
Ten years doesn't sound like much until you're standing in front of the garage, because a 1954 door opening was framed before most opener brackets existed as a standard part. The header above the door is often a single piece of lumber with no reinforced plate, and the track run to the motor mount wasn't planned for a 1/3 HP unit hanging off it.\n\nSo yes, you can buy a chain-drive kit at a hardware store and bolt it in over a weekend.
