Larry,
I used the same setup as Rich. I ordered it with a 2 speed switch instead of the adjustable delay switch since I had already heard that the delay switch presented a clearance challenge. The setup uses a flex cable drive that allows the motor to be mounted behind the passenger side kick panel.Surprisingly, it takes up less room under the dash than a stock cable drive. It also allows you to slick up the area where the original motor mounted on the firewall! The same company that makes the wiper system also made my power window conversion.
If you sell your original motor, mounting plate and transmissions, you should just about break even on the purchase of the new drive system. It comes with everything you need except the bezels and the chrome nuts that go on top of the bezels. You might want to call Billy Dawson, and see If he can't save you some money over CC.
