I went directly to Bilstein for the part numbers. Then I just googled to get the best price. As it turns out, I can buy them directly from Bilstein in Canada. In the US, you have to buy from a retailer.
Here’s the current part numbers.

Hope that helps. I’ve seen them listed on EBay with the old part numbers as well (AK2020, etc).
