I just got around to installing the by pass plug today and I went ahead removed the seat along with the plastic cover piece/side panel. Well, leave it to me as I got everything put back together, I snapped off one of the bolts that holds the side panel on. So tomorrow, I'm going to use my extractor to remove the broken threads. As for the bolt that I broke off, I think it is part # 90109-06202-00. I just ordered (2) of them from Partzilla so we shall see when they get here.
