Remove the spark plug wires from the spark plugs.
The chasm where the spark plugs are are too narrow for a standard spark plug socket.
Is there a special socket I need to buy @ a GM parts store?
The spark plug socket should fit right in there. If the plug socket you have doesn't fit, you're using the wrong one. I would suggest taking a plug to the tool store, and get the correct size that fits the plug and will fit in the hole. (There is a set size, just for the life of me, i can't remmeber the exact size, sorry)
