I am needing to install a new shower arm because my shower head needs replacing but unfortunately the shower arm that is coming out of the wall is not normal size. At first I thought that the threads were just stripped some but upon closer inspection the threads are 7/16" instead of 1/2". I have been unable so far to find a reducer to go from one to the other and was wondering what everyone suggests. I am trying to get by with not changing out everything in the wall if possible because I will have to change most of my plumbing just to change it. My house was built in the late 50's and I have run into several problems when replacing things on the plumbing.
