I didnt see any helpful stuff on the web detailing the fitment of dual H8 batteries instead of the stock H7 batteries.
The drivers side is easy, just pop the little plastic bracket on the bottom of the battery tray out, and the H8 fits.
The passenger side battery tray measured a little over 14 inches long on the bottom, but only 13 inches long at the top of the tray, so I used a dremel and trimmed the firewall side of the tray, making sure to leave a lip at the bottom to keep the battery from being able to slide rearward. There was one wire loom attached to that side of the tray so I removed the plastic push pin.
Installing the bigger battery on the passenger side was helped by removing the hood prop on that side which gives a bit more room to slide it into the tray since the battery terminals and cables are very stiff and crowd the area. Please remember to support your hood before unfastening the prop.
The last two pics are to show that you still have access to the battery hold-down bracket threads on both batteries so you can use the factory hold downs. Both hold downs were 10mm, drivers side batt terminals were 10mm, pass side batt terminals were 8mm.
