Step 5 Mounting the dome to the lower jaw will be the next task. Here is where the puzzle starts coming together.

You will see multiple photos below about measuring before drilling...take heed! Notice the lower jaw after the initial rough sanding and primer application?

Not to mention, you don't want the helmet to look like a kitchen garbage can...you know the one I'm talking about; step on the pedal and the lip opens. Due to the perspective of the camera and the viewing angle, this does not look evenly measured across the entire dome brow and lip...trust me, it is!

I highly recommend drilling the front hole on each side first. Applying one rivet at a time. Then go back to insert the rear rivets. This will allow for any final minute adjustments before you snap the last rivet. Don't forget to use washers on the backside of the rivets or the rivets will pull through the plastic when you snap them.
