One Piece ABS Headliners ??

Has anyone tried (successfully) to install one of these in an earlier model originally equipped with a cloth headliner (i.e. 1969 Swinger)? If it cannot be done, can someone describe why it won't work? The catalog states "for 1970-76 Dodge and Plymouth A-Body models originally equipped with a cardboard style headliner".

Thanks,
Jeff
