Need to know this. Is the center trans shaft from a 200 20v the same as on an S4.
 

Hi.
I am having problems with the transmision shaft.
To make a story short, what are the shafts that are interchangeable with the 200 20v's?

Someone is offering me that of a V8 and another one from an S4.

Could I could go with the S4 one without problems?

Thanks

I am editing to add some info. The original part number ( transmision shaft/propeller) of the 200 20V is 443 521 101 B and it is 1492mm long.
On the ETKA, the one from an S4/S6 is 4A0 521 101 B, and it doesn't say the length.

On another hand, where is the Part Number written? Where can it be found?

Thanks
