I read through some of the older post here, however I still have a few questions. I want to remove the oil splash guard on an 881 intake to refinish it and the carbs. I read about SS, aluminum, and steel rivets/drive rivets. I have used plenty of rivet, just not this type. I did see some post that Show Cars, GM, and McMaster Carr, to name a few sell them. So here are my questions. Best place to get them, and which ones ( SS, steel, aluminum ) ? And most importantly and my real concern is; besides an interference fit, do this come with some kind of sealer, Loctite, etc, to help keep them in? I am concerned that when I pull them out that some may be, or become lose. And when I put new ones in I don't want them vibrating out. Any suggestions, would be appreciated.
