Anyone have a good picture of the upholstery around the seat back catch on the bucket seat bottom (Dec 67 SJ built 68 Cougar - standard interior)? Assembly manual seems to show the vinyl cut around this catch but I've also been told that the catch mounts with it's 2 screws over top of the vinyl. Inclined to follow the assembly manual approach but concerned about just cutting a hole in the vinyl that could stretch and rip over time. Have the upholstery kit from Distinctive Industries. Thanks.
