These indicator switch stalks on the early baywindows are a common failure item. We are lucky to have sourced a new reproduction stalk as these are very difficult to find second hand and were unavailable for a long time.
These stalks are designed for the 68 to early 72 models. They will fit 72-74 models with some wiring modification. Unfortunately the 72-74 switches are unavailable so unless you can find a good second hand one, this is your only option.
Sold without the housing but will fit early housings and later housings with some minor modifications.Part Number: 211953513JR
