[s-cars] 5kcstq center drive shaft interchangeability with S6

[Joshua Van Tol]

Anyone know if the center drive shaft in a 5k turbo quattro will interchange
with the on the S6? I know there's some superficial differences, but they
look interchangeable to me. Anyone know for sure? I've got a rebuilt 5k
unit, and the on on my S6 has a problem with the center joint, which is
staked in on the S6, and replaceable on the 5k.
