    Steel Driveshaft in a 98 Formula????

    I was under the impression that all 98 to 02 LS1 Fbodies had an aluminum driveshaft. Mine has a steel driveshaft instead. were there certain models that came with the steel or was mine installed afterward. It's a 98 Formula M6. The car was built decently when I bought it so I'm wondering if a previous owner swapped it for the steel thinking it'd be stronger.

    Thanks for any info.

    supposedly if your car came geared with 2.73's you got a steel ds. Otherwise they were alum.
    I have an 02 that originally had 2.73's but definitely has an alum ds so go figure.

    Chances are the previous owner swapped it out like you said.
