Quick ignition coil question
 

Kind of dumb, but i'm reinstalling my ignition coils and when I put them on the brackets, all of the corners sit flush except the bottom left one (if your looking down at it facing the spark plugs (bad description, sorry). There is like a quarter inch gap, which looks like something should go there but I can't remember what, and I can't tell looking at the service manual. It's the corner next to the oil filler tube bracket and the vacuum chamber bracket. Thanks for the help.

I figured it out.
