What do you mean by popped out??? I had the FMS Adjustable Clutch kit on my 5.0. The cable came off the quadrent some how. I managed to hook it up again by reaching under the dash. I took the car to Mustang Specialteaz and it turned out we had mixed up the the way the cable gets hooked up at the clutch fork.

Hope this helps.
