Hy guys, I'm getting confused, in my experience 7/16 x 20 tpi is the thread pitch for the banjo bolt type of attachment an no line seat inside that bore. 7/16 x 24 tpi is the standard thread pitch for 1/4 brake line. Are you saying that there is a hole in your cylinders with a seat and 7/16 20 tpi? If that is the case I've never encountered it before please clarify.
