Sustain pedal plastic

[BSimon999@AOL.COM]

I will soon tune a 1978 Schafer and Sons piano for a customer 50 miles away.

She called and said that "with a bang" the sustain pedal broke. She said it 
wasn't the metal pedal, nor the pedal bearings, nor the dowel, nor the pedal 
rod, but the plastic piece that goes from the pedal to the pedal rod. White 
plastic, snapped in two.

I am unfamiliar with what she is talking about and she does not explain 
things well.  So that I might take enough supplies and equipment to repair in 
one trip, -- does anyone know what she is talking about?  Has anyone had to 
replace such a broken plastic piece?

Any help would be appreciated.

Thank you,
Bill Simon
