I want to replace the "headliner" and side upholstery of my 1998 Islander. To make a good finish the windows must be removed (I guess, since the carpet goes under the trim) and also it's time to replace the sliding channels> Does anybody has done it? If so, how it's done? Photos or videos would be appreciated. Something else, should I replace w/ carpet or try vinyl w/ foam on the back> Thanks in advance for all answers.
