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.htmWe just thought it was important to dispel the mis-information posted on this subject earlier.
