In doing work redoing the heater core, I guess I left the door ajar for too long and ran the battery down. The battery was put in by the Previous Owner in 2012 so I decided to just replace the battery. Anyway, I went to Oreilly's to get a new battery and picked up one of theirs that would work. The battery does work but does not fit the battery locking clamp on the side of the battery. What do you guys do for a replacement battery that will work with the battery mount?
