HI,
i have a henderson (2004- on) premier up and over garage door,after taking tension off spring and removing right cone and frayed cable. i took the right hand side anti drop roller spindle bracket off x 2 bolts (needed renewing).but when putting bracket back on,they was no thread to bite the screw into.then i noticed on the floor some alloy bracket.now the door is lobsided(with only one cable in operation).can still get in garage if i tilt it to one side. Is it repairable?
