Guys, toward the end of that style of control panel, Sears started putting the DD mechanism in 70 Series model washers. I had a friend of mine I used to work with here who had one of those. Freaked me out when I opened the lid and saw the difference. Even more so when I turned it on to spin and heaerd the "clank" of the coupler engaging at spin rather than the krr-grint of the wig wag for a belt drive. The time was around 1984 or 1985.
