So you thought my rattling/ticking noise was an exhaust leak?

Well, so much for exhaust rattles! If it does turn out to be your Ball/Trunnion front U-joint, fix it for good this way. The ball & trunnion is a very good design that does a fine job for a long time, but at this late date the parts are old and it's less expensive and easier in the long run to convert to cross/roller.
