Need Part between Brake Sensor Pedal and Brake Booster

[SUBdude]

In doing the Brake Pedal Sensor fix, I damaged the plastic housing that is part of the brake booster where the brake pedal sensor seats. I'd hate to have to replace the entire booster for that one part. Does anyone know if there's a C30 brake booster repair kit or some other way of repairing/replacing this part? It looks as if some collar that fit just right and squeezed the housing around the sensor could work, but I'm really stuck at the moment. Any help would be greatly appreciated.
