Young Chang damper tray removal

[Farrell]

Have a Young Chang 150 cm grand in a church, damper tray hinges on 3 flanges, center pins have fallen out of flanges. It appears the only way to remove the flanges and the tray requires separating all the leaded damper blocks from the damper wires and then the whole unit will come out to be repinned. Is anyone aware of any short cut to do this repinning without taking all the dmpers out? 

Thank you.
