I'd check that output shaft first. Both of my mustangs had extreme wear on the driveshaft yoke when I had the vibration like you're describing. Matter of fact, I believe I have a video and made a thread about this same problem.

Don't worry about replacing it, just yet. Go drive without it and see if the problem is gone.

It really sounds like you could have a bad harmonic balancer. I would check it too and make sure its not wobbling.
