For most of these vehicles you simply have to remove the upper and lower bolts holding the shock and remove it.
Your best bet is to purchase a service manual for this vehicle so that you can see pictures of the procedure, and you have the proper torque specs for tightening the bolts once you put in the new shocks.
I know when I did mine, the hardest part was getting the bolts out because the vehicle was so old. You may need access to a torch to heat the bolts so you can remove them. Good luck.
