1970 340 Plymouth Valiant/Duster Over Flow Bottle

I got templates to make the flanges on it if using on a 67-69 A body. The hole in side of the neck is a pipe tap, then I just stuck a set screw in the other side of the neck.

I glued .125" 2024T3 aluminum brackets in place I fabbed up with JB weld, then drilled and riveted with solid aluminum aircraft rivets.
