Where can I get factory replacement lift supports for the hatch?

I've ordered some online, and they don't fit. When I check all my local auto stores, they're all wrong. In that, they only have the ball joint attachment 1 end instead of both.

I got them for $22 each from http://www.importrp.com/ Part number 926 51012 366

They fit.
