That would be your throwout bearing. Best way to go is an OEM FORD Throwout bearing from your local Ford dealer, or a Ford Racing throwout bearing. Do yourself a favor and get a new pilot bearing aswell, best to change them at the same time. Also get an oem ford pilot bearing or ford racing.
I told the misses that I hoped it wasn't the throw-out bearing. Its been 20 years since I changed one. Im not a young man anymore. I guess its time to see what a shop will charge. If its outrageous, I can do it with the help of my daughters husband, but he has projects of his own that take up his time. Everything else is tight, so it should be a fairly quick job.
I ended up getting my Mustang because the kid I bought it from didn't want to spend $500 for a shop to change the clutch. I told him I'd do it for $250+parts and it still wasn't cheap enough. So I ended buying the car for $2500. That was 7 years ago.
