Hey, thanks for the guide…I’m wondering about something, that maybe you could help me with… I love the look of the older ,pre 1980 hazard switch, is it possible to change the newer style switch, to the older bigger switch…even just to change the cover, to make it look like the old one would be fine…..What do you think?…thañks…Michael

Hellow there, the older switch is diferent, it works by pushing it down to activate it, rahter than pivoting like the newer style, I thing the easy solution is to massure the old style switch and bore the center consol to make it fit, the console is easy to remove, and its all plastic, or wood, so shouldent be hard to bore the hole. The switch stays in place by pressure
