I did another H2 set on my H3 and have no gap. I used the factory bolts and nuts. Just had to dremel off the extending screw threads. Pull it in taught and no gap anymore. My fist attempt was good but the gap was not. This works flawless and looks great. HOWEVER the Chrome H2 handles will crack your panel. I know this from experience so DO NOT try and get them flush. (THEY DONT FLEX AT ALL).
Good Luck
