I'm looking to get a 2-speed wiper motor for my 1965 Mustang. However, all I can find are 1-speed motors for my car. It looks like the 2-speed motor from 67-73 Mustangs will mount right up, but I'm not sure. Anyone have any info on the upgrade? I really want to have 2-speed wipers. I've also found a 2-speed wiper switch with upto a 15sec delay, so that with 2-speed wipers will make my Mustang even better.

Thanks in advance.
