2speed to 3speed wiper changeover

sure!! pictures are available right here.

the top one is a 2 speed set-up, the bottom is the back side of a the vari wipe switch in a 69 dash.

the bushing used on the vari wiper is different than the 2 speed set-up-- they also said the motor arm to wiper transmission is different-- i did not notice a difference when I installed mine-- but did not look that close. Lawrence
