I recently bought an 84 corvette with around 60k on it. First i Put new SS magnaflow on because when i put it into gear I would hear this tinny clank. I thought it was the mufflers, they did rattle. After spending way to much money at the exhaust place, I heard the same noise exiting the parking lot. Now I figured it must be the u-joints on the drive shaft. Swapped those out. The main drive shaft and the right rear. You can still hear it. Now i just took it to a shop to have the one remaining side done and they told me i wasn't the U-joint but the rear hub assembly. What do you guys think?
