Source for exhaust hangers

[Austin Calise]

Kenneth, the rear hangers are used on the Porsche 944 924 928 951
so you'll be able to find them in the aftermarket and even OEM for less than the audi dealer online or not.
92811125902 Here's a pn# cross reference list http://www.findpart.org/part/fa1-113928
Now the other donut 893253147F for the connection to the rear diff cross-member is just a generic donut
cheap enough to replace every time it wears out.
FYI I've never had to replace one of the rear hangers they just don't seem to wear out.
