Hi I’ve got a 2007 2.7 S type with a sun roof unfortunately it’s suffering from the dreaded floppy headliner I looked on you tube and thought I had a fibre glass base to work with, when I removed it I found I had a flimsy foam outer frame. Does anyone know if there is any after market headliners I looked on eBay and there’s two models available but none of them right for my vehicle can anyone help regards Steve
