How strong are the stock rear ends?
 

I've noticed that when I start on an incline that my rear end tends to do a little shake until the clutch is all the way let out and I'm underway. I've been pretty easy on the car in the ~1000 miles I've owned it, and it was stock when I got it, but it had a pretty hard life before me.

Normally I wouldn't be that worried about it because all of the 6-speed F-bodies I've driven do the same thing everytime they leave a light, but I just wanted the peace of mind that my rear end isn't going to grenade on me. :)
