I have run 9 speed gripshift forever and never broke a shifter. Been running XX gripshift for a few months and somehow broke the female threaded part that the barrel adjuster goes into.

The part is separate from the main body and mounts with a torx screw. It was clearly designed to be replaceable, but the spare parts catalog doesn't list this as available as a part.

This part should be available... Anyone have a part number? Happy to pay for the part as I am sure it was my fault (no idea how I broke it though), just can't find it.
