The aluminum driveshafts were sort of hit or miss. My 94 Z28 M6 came with one while my wifes 96 Z28 A4 vert did not. 
Very limited production Camaro intended for showroom stock type racing. Better suspension, brakes, etc. Most of them also had no A/C or power windows/locks.

thankd for the help guys. My buddy and i figured it was possible because the 97 had some LS1 model components. (tail lights, interior etc.) figured maybe they put the aluminum shaft in as an extra benefit. So uhh what kind of performance gain could i see over an aluminum shaft?

Q: What's included in the 1LE performance package?
A: The package required these options (Z28/Formula, respectively):
Basic option group (FZAB/1SA)
A/C delete (until 1996 when A/C became standard)
6-speed transmission or performance rear axle with the automatic (GU5/G92)
Z-rated tires w/ 150 speedo (QLC/QLC)
Base stereo
and it consisted of:
Higher rate front springs (360 lbs/in for mid-1994 and after)
Variable rate rear springs (130-180 lbs/in for mid-1994 and after)
Stiffer front and rear shocks (Koni double adjustable for 1996 and after)
Harder bushings (front upper/lower and rear control arms)
Larger diameter anti-sway bars (32mm front, 21mm/19mm rear)
Increased cooling (for 1995 and after)
Engine oil cooler (1993 - 1995)
Stronger Transmission mount for 6 speed Transmission's
Stiffer Panhard-bar bushings
The 1993 1LE cars had the same springs and deCarbon shocks (but with much stiffer valving) as on the stock Z28s and Formulas. Initial 1994 1LE cars received the same set-up, but sometime during model year (between Dec 94 and Mar 95), the 1LEs received stiffer (higher/variable rate) springs and the shock valving was slightly reduced (but still considerably stiffer than the stock deCarbon valving). Due to the stiffer springs and modified valving, the 21mm rear sway bar was dropped in favor of the 19mm bar (which was the same as on the stock Z28s and Formulas). In 1996, the Koni double adjustable shocks became standard on the 1LE cars. Increased cooling on 1995 and after models was accomplished by the addition of an air conditioning radiator baffle even though no AC was available in 1995. Also, after 1995, in order to get the 1LE on the Firebird or Trans Am you had to order the WS6 package. According to the 1997 Pontiac brochure, the 1LE package could not be ordered with the automatic transmission.
