Yes, you just need all the components, and a three speed wiper motor with switch, and the plastic bushing for the arms for the motor too.
you can cut the base to fit with a two speed motor but the airgrabber seal would still hit the motor, and the base wouldn’t be sealed to benefit from the cold outside air as the cut portion could/would suck air from the hot engine bay because of the notch cut in it. Attached is an example of a base that was cut so you can better see what I’m taking about.
and yes, the 383 and 440 bases are different heights. Choose accordingly.
it’s a costly endeavour
