Variable speed wipers

My 67 Dodge Dart 270 4 door had the variable speed windshield wipers, my 67 Gt Conv. has the standard 2 speed wipers. I have always wondered what would it take to convert the GT over to the variable speed wipers?

yup. Just swap the switch, motor and the extra wire harness on the var.,speed switch into your 'vert. The crank is the same.
