Rear axle bush Helpee!!!

Hello, I wanted to change the bushings on the rear axle, which are on the handlebar pointing forward, are 2 single bushings one from right one from left, ordered them from Audi, of course had my vehicle license with it, got the bushings the next day, expanded the old ones, wanted to install the new ones, are in diameter too big, old ones built again! I brought them back, ordered new ones, are even bigger!!! I've re-developed the old ones, I've got this number. found on it: 443511247D On the invoice was exactly this no. This may be the number number. was right and in the bag the wrong camps, I have no idea anymore, the ones of Audi either! The Audimann first had the Audi 100 with star axle on the screen until I told him that it was a v8!!!
Hope someone can help me!
Thank you very much: Gruss Kai
