The distribution brake line block on the rear of an AD master cylinder is not available new (that I can find) so going to machine some. It is the fitting that is held to the m-c with a hollow banjo bolt. Although I use a lathe and mill on a daily basis I am NOT a trained machinist and have run into a problem. The OD of the flare seat is larger than the ID of the fitting threads so a tool to cut the seat cannot pass through the threads without cutting them away. Any suggestions ???
