Very old Cuisinart DLC 7e food processor

I have a very old (over 33 years!) Cuisinart DLC 7e 14 cup food processor that is still going strong, but I am in dire need of replacement parts. I need a new work bowl to replace the original, which is held together with tape. More importantly, I need a new metal blade.

Does anyone know of places in the twin cities where I might find old Cuisinart fp parts? I would even buy an entire fp and then use parts from it as needed.

Thanks, guys.
