[urq] URQ front rotors

[ANTHONY ATTARD]

Hi everyone. 
Some years back I had upgraded the front brakes (Calipers and rotors, single piston to two pistons, etc.) on my 1983 URQ.  Unfortunately, I did not keep notes as what year the upgrades came from.  I think they were from an 1985/6 Audi 5000 Turbo.  But I am not sure. Now I need to replace the rotors, but I have no way of knowing what year or model they came from.  So I took the rotors of the car in the hope of seeing a part number stamped somewhere.  But I could not see one.  I do have numbers for the calipers.  Any help would be greatly appreciated.  Thanks in advance.
