4th gen driveshafts

Did all 4th gen Z28's come with aluminum driveshafts? My 91 RS has a vibration at 68mph+ that I believe is the driveshaft. Since I am going to have that driveshaft out while changing my gears in a couple of weeks. I found a 95 Z28 at a local yard for $50

. Got to love www.car-part.com

I just can't see under it to tell if it is aluminum or not. They won't pull until its paid for. I figure it will cost me at least $50 to just have mine balanced.

No, not all 4th gens have aluminum driveshafts. However there was a TSB that 4th gen owners could get their driveshaft swapped to an aluminum one if they complained to the dealer. So who knows if that one is or not, so make sure before you buy it.
