The end caps, bumper, and rear hitch bolts all needed to be removed before anything could go on. Detours suggest you remove the hitch and put it on later but you don't need to. You can use it as your bottom plating for the L-brackets and the inner cross member has to be angled between it and the cargo floor. Those a re the only two hiccups you have and they're taken care of in about 10 minutes.
