I know TC carpets were discussed a few months ago, in fact I went back and looked over the thread and also read through TCs Forever but I still have several questions. I bought a Moss carpet kit and am trying to install it in TC 7387. When I bought the car, it had a totally unoriginal interior. My other car, TC 0857, didn't have any interior installed. So I have absolutely nothing to go by as an example. First, I'm not overly impressed with the MOSS kit. It seems to be adequate, though. The carpets are almost right, but will need considerable trimming. It came with 5 lift-the-dot fasteners and 5 hidden stud fasteners. I suspect that is not enough. The instructions sheet doesn't have much detail. Only says the prop shaft tunnel carpet goes under the floorboards and the front carpets overlap the rear carpets. No other details. My questions: Should the prop shaft tunnel carpet go under the floorboards? Or would it be better to trim it off and glue it on above the floor boards? If I put it under the floor boards, do I still need to glue it down? Anyone have any idea of how many fasteners there are and where they are located? I count at least 7 lift-the-dot studs on the metal foot ramp. I have absolutely no idea about the rest of the fasteners. I remember seeing a diagram of how the rear carpets have an L shaped cutout for the seat track mounts. Anyone know where I can find it again? Regards, Charles Hill
