I have been looking at the different brands of flipping tonneau for my 8 ft bed. I'm thinking of the RAM version. The problem seems to be that while the tonneau itself is available and in the accessory catalog, a required part number (82211302, rails and locks) has been discontinued. If anyone has any more information on ordering these, I'd really appreciate your insight. So far, I think the tonneau is 82216490AA. Thanks very much.
