When the old switch failed a couple weeks ago, I decided to do something different than the shifter mounted switch.
Took a couple hours to figure out the arrangements and get proper fitting hardware from my leftovers and odd-and-ends bin, but here is my new shifter and injector cut off.
The injector toggle is mounted on my DIY center console "instrument panel." The new shifter is a primed and painted kids candy box of some kind that I found in the street a couple years ago. It is made of really strong plastic and had a "gear-shifter-ready" ergonomic shape. Only purchase was the $3.50 for the toggle.
