At risk of driving you all crazy, I was not paying attention to the battery discussion last week, and was wondering if there was any final consensus/conclusion? Yes, my 85's OEM battery died over the weekend. Has anyone fitted an Optima into their Ur-Q? If so which model, where can I get one, and is fitting an issue? TIA.
