I should have covered the shocks a little better in this pictorial, but you can get the general feel of it. Like BigSwede says, it's just nuts and bolts. I suggest liberal soaking with PB Blaster. I felt that just a few more inch-pounds on the breaker bar getting the nuts off would have twisted the shock mounts off.
If you aren't familiar with the pin-type of front shock upper mount, just tighten down the nut on top until the rubber bushing is squeezed even with the edges of the metal washer thingys, no further. This will make more sense when you are looking at it.
Mine were a friggen bear to get off (damn CT winters!) The top bolts on the rears didn't want to budge but eventually my dad got them for me. The bottom nut n bolt snapped on the front drivers side but those are easy to replace a trip to the hardware store for some grade 8 goodness and all set with that. The only REALLY big PITA was that the shocks Pro Comp 9000s the rubber bushing holes were small and didn't want to fit on the metal bolt studs on the rears literally had to push them with our feet.
