Here is a link to "Usautoparts". I'm not opposed to buying from somewhere else, if I could get it cheaper, but I have bought from this place before and they have been legit. Anyway, my current rack says "koyo" on it and that would eliminate most of the options on this page but the top two are for "koyo" racks but they are slightly different.......how do I know which one fits my car?

US Auto Parts - Catalogs - 1998 Audi A4 Quattro Steering Rack Stock Replacement

 

My system shows they Koyo used in the 4 cylinder application only. But if I'm reading it correctly, the 2nd rack that is more expensive includes the inner tie rods, you'd reuse your outers.

 

thank you

 

Just to throw it out there, if you want to save some good money on the purchase of a rack, id buy a used one from Shokan parts. they have a website, and theyre an audi salvage yard where they get in totaled cars and take off every part from the cars thats in good shape and worth selling and they clean them all up.. when i replaced my rack, i looked all over for the best deal and the closest i got was like 450.. got a used one from Shokan at 120k miles for around $200 and im now around 160k miles and not a problem.. would do it again in an instant if i had to.. just my2cents
