If the alternator is the only thing that needs protection I think I'll just "fab" some kind of aluminum splash shield for the area around the alternator and call it a day.
Mine self destructed when I took my mopar skid plate off. Apparently the bolts for the skidplate hold it in place, and during a turn it hung down far enough to get caught by the tire.
For those who may be wondering..... I took the skid off because I was going to be doing front-end work the following weekend. That thing is nothing but in the way for getting to anything down there, i.e. the pitman arm tie rod end, track-bar mount, etc. I'll probably replace it after I put my lift on.
