my own design
I used a small wiper motor from a Ford Bronco with self park, Made my own adapter bracket to mount to the firewall then used bearing shaft lock collars to make arms and welded. attached this to the stock transmissions with set screws in the collar, same type adapter to the motor. conected the two with threaded rod and heim joints for adjustment and set to go. No cables no Vacumn, Total investment about 60 dollars.
