[urq] Brake servo difference?

Yes, you imagine you can.  I did so with the clutch master on my '83  
in Steamboat 3? years ago IIRC.  I ended up using the clutch master  
from a 1990 Coupe quattro, but as you say, the plunger rod is unique  
to the Urq.  You will need a circlip remover and at the same time  
putting pressure on the piston.  Also, be careful (maybe want to do  
this operation with a box on top) in case the whole assembly springs  
into pieces -- I should know.  I forget if I rebuilt mine using the  
other pieces or whether I just switched the rods.

In any case, just make sure the fittings and locations for the brake  
master are the same.  I should imagine the brake master setup at the  
plunger rod is not so far removed from the clutch master setup.

Best of luck.
