Does anyone have the "windstop" for the 2003-2004 convertible? It's shown in the 2004 online brochure but I can't find closeup pictures of it anywhere. I basically want to know if: a) the thing is effective b) my kids can still ride in the back with it installed c) is it worth the $250 it appears to cost? (probably not but there isn't a lot of choice) Ford part number is 2R3Z76539A18AA-258 and its description is Windstop. It also looks like it is made by a company called ORIS (www.oris-ltd.com). Thanks in advance!
