I ordered it off of that ebay link. The price is higher than Arnott, but it actually includes shipping, as well as the return shipping of the core. If you zoom in on the strut, it actually says Arnott all over it, so I guess they are a re-seller.

Description says 2 year warranty.

Anyway, hopefully this does the trick. Thanks for the help.
