I stand corrected! Yea,NOW I remember the "bicycle bell" style switch used on the A.D.'s. My T.F.'55 has a different set-up entirely. I have electric wipers,so I'm sure my line, "flopping in the breeze",attaches to the speedo,when I can locate the part. Sorry for the mistake. The origional location for the 2-speed switch,(on my truck),was mounted on the tranny.The cable is mounted on the shift rod.
