    MK IV kit delivered in Spring 2013. Got a good start, but had to focus elsewhere. Moved. Now get to spend a couple days a week. Not a show car; not a race car. Just a very clean build with lots of help from the Forum.
  4. Converting Speedometer to GPS

    Factory Five Roadsters
    I purchased a Dakota Digital model GPS-50-2 to connect to a 2001 Mustang Cobra speedometer from a donor for my Mk IV. They tell me that it cannot be CanBus which Ford tells me didn't happen until 2004, so I'm assuming this speedometer will work. There are four pins out of the Mustang...
