Ignition Rotor

[Rene Curry <curry@ili.net>]

I have an 84 Audi 5000 Turbo with a FWD slushbox.  I been trying to buy a distributor ignition rotor by giving the year, model, etc for information and everyone gives me the wrong rotor.  I can solve that problem next week by using the Bosch number on my existing rotor but I am wondering since I bought the car used if someone changed something.  My existing rotor is part number 1234 33 2374 and the distributor has a small diameter shaft compared to the rotor they try to sell me which is 1234 33 2301 which has a larger diameter hole.  
Do you think someone changed the distributor in the past or are there multiple distributor versions? Euro version? 
 
Thanks in advance,

Hey, What did they call the Audi that fell off the bridge crossing the river?
