Call me a Sears redneck, but if it's not an Optima, it's a Die Hard. I had this '83 with a 351W for about 2 years, and i bought one for it when i got the car. Over those 2 years of trying to get the car running right, and cranking cranking cranking, never getting any alternator charge or anything, and sitting outside for those 2 years, it held a charge. I pulled it out and dropped it in my current '85 and it fired right up. Die Hard Gold.
