I replaced it with one I got from shonutperformance. The local ford dealership told me that the parts were discontinued. It's two very simple pieces of plastic but a huge difference in shifting. $32 from shonutperformance plus shipping.(my cheapest fix yet and one of the more noticable ones)
Yes, the rod shifter has to come down, actually very simple just remove the two rear nuts that hold the box on, remove the inside shifter ****, remove the two rods that go to the transmission and it just comes down. Once it's down just take the 6 small screws out of the black box so the two rods come out and you will see the ball at the end of the shifter handle and the socket which is on the shifter rod. Replace and put back together.(when replacing the socket you have to drill out two rivets to remove the plate that holds the socket in--I actually taped mine out with a punch)
