This enclosure is not compatible with the sun tops supplied with E-Z-GO RXV vehicles built before August of 2008. This enclosure includes aluminum rails that mount under the sun top with rivets. Attachment at the windshield is with velcro sleeves that attach under the windshield clips. Attachment at the bottom of the vehicle is with web straps and hooks that hook to the vehicle under the rocker panels. Be careful when installing that the rear panel goes inside the rear sun top struts.
