Thought I would start a tread on my adventures of doing a Mustang Base to a Track Apps swap and update as I go. I found two clusters. One from a 2014 6cyl Mustang from $125 with 18,000 miles and another from a 2014 GT with 28,000 miles for $200. I am going to buy both. The GT is within 1 hour drive so I intend to pick that up soon. The other is too far to drive so they will have it shipped. Right now I have a little less the 18,000 miles on the Base Cluster. I already installed what is called the "OK" switch which works with both the Base and Trackapp cluster. Picture of Base Cluster to be replaced.
