How do you get to the rear spark plugs to replace them on a 1996 Corsica that has the 3100 SFI V6?

I recintly replaced the rear spark plugs on my 1995 corsica V6. It is almost imposible to see the plugs so when you remove the wires feel the location of the spark plugs and rememberr where they are. I was able to replace all 3 with just a rachet. you will have to find the best space to get both hands through the wiring to access the recess where the plugs are. after removing the old plugs it is just a long process of working you hands into the tight space to thread in the new plugs. I accomplished all of this on my car from the passenger side of the engine compartment. I also just did this on my 95 Corsica with the 3.1 It is very difficult and i was unable to do it as the other suggests. I took the coils off the top (where the plug wires start in case you dont know) and then from there i took all the other connectors off and vacuum lines. Then i was able to set that out of the way and i could see the wires and plugs. It is still not easy, i ended up laying on the motor from the front. Its not too bad, just tight spaces. Good Luck
