I got the battery from Antique Auto Battery because it was the only place I found that had the license to make exact repro's.I asked the lady there if it was an Optima inside the case and she said it was a different brand.When I got the paperwork it listed a charger for Odyssey batteries only,so I assume that is what is inside.It was $266 shipped,which almost stopped my heart,but now that I have it here it looks really nice in the car.Thanks again.MW
