Just FYI, owner's manual is
here. I didn't see a part number for the front handle. 121364-01 is the part number for the main handle assembly, but I'm not sure that's waht you need.
The distributors for Remington chainsaw parts are Master Distributors. Their website is
here, but I suggest you call them at 888-917-2244.
