LCA pin loose in bushing

From other experiences I decided to look at the last two ACDelco bushings that I bought 7 months ago from Rock Auto. I bought six at that time. I have installed four and they were fine. The last two were for my GTS. Well, one of them is loose. I just sent a message to ACDelco since Rock Auto will not warranty them after this long. Sucks as they have a lifetime warranty...I do have an old stock McQuay Norris on the shelf that I may use...
