An update: I thought about it a while and decided to call ARB about possible fixes. Hey, it never hurts to ask!
Mitch at ARB says that it wont hurt anything to install it they way it is. If I didn't want that option, he said he had another rear leaf that he could take apart and send me the new section. I opted for that and just got the part via UPS today. No questions, no cost to me.
