How do you remove replace the gear shift knob on a 1995 Eldorado ETC floor shift?

The 89 and 93 Eldorados have a U-shaped pin that goes into the leather from the front of the car. It is very hard to see, and even harder to get to come out. It works like a Key Pin and once removed, alows the whole top of the shifter to come off. It is pretty small and flat, just like a spring. I took mine off to get access to removal of the center console.
