I just got a 1979 caprice ( the 3rd one I have owned ).
This car is clean and un-molested and it has cruise control. The lever on the steering column was replaced at some point and a stainless steel aftermarket lever was installed instead. This lever does not have the engage-button in the end. I am searching for the right lever.
Meanwhile I have wondered how to control activation of the cruise control.
I can not find any on/off switch anywhere on the dash ?
