Need a Audi 200 20v 3B distributor

[Bernie Benz]

Your impression is wrong, I have used them interchangeably in both  
engines. The two distributors have different part numbers but the  
only diff I found was that the 3B had a plastic shield between the  
Hall area and the rotor, the 7A did not. A small sample lot evaluation.

The 3B rotor is identical to the 7A rotor excepting for the width of  
the tip. A 7A rotor can be converted into a 3B rotor by filing the  
tip sides to an overall width of 0.435”.

3B rotor: Bosch 1 234 332 414 R1
7A rotor: Bosch 1 234 332 301 R1
