Can someone please help my friend someone switched batteries with him and it failed he has a 2002 fxdwg. Since his forks have been changed he don´t know what size of battery he needs to get, plus it won´t do him any good to check the L,W,H of the battery that´s in it since it´s the wrong one. Can someone help him out here and please tell him the actual L,W,H of correct battery. Need a battery to get it back on the road please the right one..
