i have a 2005ish shelby mustang drive shaft.
a friend of mine only removed it because he was about to super charge his mustang and he just wanted a newer drive shaft.
it's rated up to 500 i do believe the product number is 8R3V-4K145-AA
i'm not even sure if any of you have much use for it.
but if you want it just make me an offer.
I'll put up pictures soon.
