No they will not bolt in, and you cannot bolt the tracks from the 79-04 stangs onto the 05's. I had a set and I sold them to a guy with a notch. He new they were different set up and I never heard back from him...but you will need to do some custom fabrication on custom tracks. I saw the bottom of the 07 seats and those look a little bit different and easier to make fit than the 05's.
