Hi, sorry I don't post much but I really need some help.

Here it goes. I've got a 01 z28 with a 6 speed and it just hit 67k miles. When accelerating from 1st gear usually the car will vibrate REALLY bad and it sort of shudders from the rear somewhere. Its hard to explain, it kind of sounds like a piece of metal is slapping another piece of metal. I replaced the transmission mount with a poly mount and know there is a little vibration after installing one but it shouldn't be as bad as it is. I also replaced the u joints on the drive shaft and it still has these problems. The car is almost unbearable to drive and I'm really getting fed up with it.

Those are the details, has anyone ever had a problem like that? I tried searching but I couldn't find anything that sounded like my problem. Thanks in advance.
