Thats strange, Vagcat and ETKA list these for a 1985 Audi 90 with the following engine codes: CY,JL,JS,
HP,HV,KV,KX. (which i presume are 5 cylinder because KV and JS are) The part number is 853 615 125 from Audi. If i remember correctly, the distance between the mounting holes is 75mm, which is the same as your photo
The B3 Audi 90's changed the front brakes, possibly to 95mm like the mk2 golf 16v
If easier to find, the Scirocco GTX 16v also has the 853 615 125 front brake carriers.
