I’ve just fitted some after market seat covers from Uk custom covers (faux leather Bentley stitch) to the front seats, they look good and are a reasonable fit but the extra material has made the buckle of the centre bench seatbelt almost impossible to access. Has anyone else had this and found a solution? Can’t see a way to move the mounting, so assume some sort of extension is required, but have concerns about the safety of this option. Are there approved ‘extenders’ out there? TIA
