Thanks all for your responses! Is the tumbler easy to remove? I do have time on my side as my primary vehicle is an 03 Expedition. This car has a lot of sentimental value to me. I had just stared working for my dad and was there when he bought it. And have vivid memories of him handing over the check. I've got the pink slip so I assume I should have no problems getting the parts. I'm fairly handy with tools, so is this something some one with medium skills can handle? Also what service manual do you suggest I get?

Again thanks all for your responses.... This is a great group!
