If your Cuisinart food processor was made before 1988, contact Cuisinart for parts and/or trade-up options.
Some part numbers may have changed since your Instruction Manual was first written. Most retain the same beginning letters and numbers, with only letters (e.g., TX) and/or numbers (e.g., -1) added to denote certain revisions. The letter 'G' was added for parts made of Grey lexan.
Bowl designs have changed over the years to increase safety. Compare the model number on your old bowl and lid to the new parts; if different, you will likely need to replace both the bowl and the cover.
