[V8] Where to buy a new driveshaft bearing?

[toml99 at todomundo.com]

Somewhere in the Archives/in my Audi folder is someone who used one  
off an MB something...I'll see if I can find it unless someone will  
chime in which needed a little something to make it fit.  Option #2 
(which I may do on the 5-speed as it's vibrating a little) is having  
a 1 piece aluminum driveshaft made using your ends....a few have done  
it with no complaints.  One guy was around $200, and the other was  
$450 as I recall...Tom
