Hi George,
good choice on the Lifeline Batteries. There is a Lifeline wholesaler in San Dimas, California, phone (909) 599-7816. I bought 10 lifelines, 4 house, 6 starting for, my ‘07 Marquis at a substantial discount from these people. Shipping was very reasonable. Can’t hurt to give them a call and get a quote. I saved several hundred dollars over the local supplier here in Grand Junction. Hope this helps.
