Fixing the Windshield Wiper Switch

This is a delicate part in a Spitfire. They designed a switch with a push pump for the wiper fluid that also controls the speed. As far as I know this part is no longer available. During the disassembly of the dash the switch arm broke. I decided to fix it using a brass sleeve and super glue mixed with baking soda. Shown below is the before and after photos. I used a setscrew to attach to the arm and had to drill our the switch knob a bit to fit the sleeve.
