For anyone that is looking for one of these '97+ "soft" covers, I think that they came stock with all the UpCountry Suspension Group XJs. Might help with narrowing your search.
Hate to drag this thread back up, but.........................Have any of you noticed a difference in interior buffeting with this cover in place? I've been running 4 down @ whatevers posted off and on and noticed between this cover and the VentVisors seemed to all but get rid of that strange pressure change I've always noticed in our XJ's.
