Dear Valued Home Depot Customer, We reached out to MFG for more information and below is their response. "The model number and the part number are the same number. "
This kit is designed for use only with the PowerMaster Plus. Please contact ITW Construction Parts and Service at (866)-749-3391 to find the correct parts for your tool.
You will need to contact DeWalt regarding this question.
You can purchase the F350 repair kit on homedepot.com or you can contact your local Home Depot store to inquire about availability. If the kit is not available at your local store, the store should be able to tell you which stores carry the product or they can special order it for you.
