Rear seat? How do I get to it?

Pull the lower seat cushion up from the front. It will pop right up.

OK guys,

I checked out the Costco group 78 battery. Similar in size to the 79, but no vent holes up top. It'* a shame that Costco is telling people this is a direct replacement to our battery. Could be very dangerous to have those battery gases circulating around the passenger compartment. I went with the Duralast 79-DLG.
