Help 2001 Dakota

The battery in my 2006 Dakota got really corroded really fast even after a cleaning. I finally saw a crack in the casing and think that may have been causing the corrosion. The corrosion was so bad that I basically had to break the terminal to separate it from the cable (not sure if the 2001s are the same way, but my battery cable has a bolt that connects to the terminal thing that you put on the battery. It is a really neat idea, I think, so that you only have to replace one part and not the whole cable). Turns out that dodge doesn't sell the end pieces to the battery cable, so I bought a generic piece that was a little big and clamped it down really good.
