A3 rear bump stops

[S70JPS]

The bump stops have come apart on my A3 leaving a rattling ring of metal around the shock. I plan to just cut the ring of metal off and replace them properly next weekend. The problem is I can't seem to find them for sale on the net. I've seen some on ebay but they look different. The car is an 05 1.6. Could anyone point me in the right direction. I don't want to pay main dealer prices.
