Needed a few extra parts for a TH400 rebuild. These all were as good as the ones in the kit I had bought. Don’t know why the kit didn’t have everything but I was glad to find an additional kit without having to explain what I needed to some moron at my FLAPS.

Does not come with the correct pieces for a th400. Missing some, and has extras that don’t belong.
