can I use a 2 speed wiper motor instead of a 3 speed on a 1974 duster,and will I need a new pig tail and switch if it bolts up. Or what are some other options to have working wipers on my project. Obviously not doing a restore more of a resto mod. Just want to have working wipers, and a decent looking motor where I have to look at it in the engine bay. Any suggestions or help would be greatly appreciated.
