Coil Pack Screws-Change Plugs

[joeg59]

Getting ready to change plugs and wires on my 98 Aurora. I know I need to remove the coil pack at the back of the engine to get to the back 4 plugs. I also know there are 4 bolts on the coil, but I can only see two. Can someone tell me where the other two are or is there a picture or diagram of the coil?

Thanks

I Think The Four Coils Only Have Two Screws Per Coil. When I Change Out My Back Plugs I Just Use A Universal Adapter, 3" Extension And A 6" Extension. I Dont Bother Taking The Coils Off.
