I am in need of a new battery side cover for my '02 super glide. I have noticed that harley makes two models one for the standard battery and one for the AGM sealed battery. Apparently there is a slightly different shape with the AGM battery. I currently have the old fashioned battery and plan on using it until it dies and will then go to the AGM. I would hate to buy a new cover for the battery I have and then have to get another one once I make the switch. If I go ahead and get the AGM size cover will it still fit for my current battery?
