did they ever have back up lights on a 61 gmc with a 4 speed trans .if so how was it hooked up ,if not how can they be hooked up ?thanks
first item here
- mechanically actuated by the shifter
Incorrect Bill. That is not a switch for a 4 speed.
Here is the original GM mechanical back up light switch that mounts on the 4 speed shifter.http://members.cox.net/images4755/scan0001.jpghttp://members.cox.net/images4755/Img_4379.jpg
that had me stumped ,and now this clears the fog away from my brain !i wonder if this is still available with the harness ?
I've heard reports that the 67 SM420 had a reverse switch, or are the links "Mother Trucker" switch it?
That GM backup light switch posted by M.T. will work on any SM 420 4 speed from 1947 to 1967. http://www.novak-adapt.com/catalog/sm420_parts.htm
We just thought it was important to dispel the mis-information posted on this subject earlier.
