There were two styles of towers that came on the 2005 X2 -- the older style that is shown in the pic you posted as well as the newer style which is on my 05 X2. See pic below.
Can you confirm if covers for both styles are available? (The opening for the rear legs on the newer style tower are further back than the older style, so the covers are different.)
Also, where on your website do I find the OEM mooring covers that you mentioned?
