[1993LUMINATOR]

buddie you can change the front 3plugs easly
Now the rear are a "BITCH" you must have car on a flat surface, remove dog bones(the 2 engine mounts engine bolts only)
and will all your might pull the engine towards you, and line the bolt holes in the lower par of the dog bone with the mount on the engine, and jam one of ur bolts thew it and it will hold the engine forward
easyest way l found then was to go on the side of the altinator and jam ur arm back there and take pluges out one at a time,
for the center one watch the O2 sencer in the exhaust,and now change plugs
But watch sence its tight its hard to make sure you have them ni all the way, the far on rear part of engine by tranny is hard to line up so must use deep scocket and get in with fingers then wratchet.

hope that helps
