Where can I find spare parts for my Cusinart DLC-7 Super Pro?

I just bought a Cuisinart DLC-7 Super Pro which was used very little and is in excelent condition.
However, the seller was reckless when packing it for shipment, such that the black plastic part which is the bottom part of the motor base (where the rubber feet are) was broken in the way.
I would like to replace this part to make this unit operational again, as all the rest is really fine.
Can someone tell me where I can find this spare part?!
NOTE: I have already written Cuisinart Customer Service, but they do not carry it anymore.

Thanks in advance for your help.
