The guy came and took my 85 Firebird today. I was REAL lucky to have had enough in it to back it out of my driveway, about 75 feet in reverse, then forward about 80 feet. The obnoxious knocking sound (that I had told yall nothing about) seems to be coming from the flex plate. My friend in Savannah suggested either spun bearings or a thrown rod. I hope it aint the engine. Anyway, he said to call tomorrow for the diagnosis, and expect it to be done on Tuesday, MAYBE Monday. More to follow.
