Now I can not be 100% sure about this being correct 'cause I used what was available on the car when I bought my tonneau, but on my BJ7 there are two tenax fasteners at the top of the rear shroud for the rear of the tonneau, there is one tenax each side just behind the doors just behind the chrome finisher, there are three lift a dots along the top of the dash board - one in each corner near the quarter lights and the third is holding the passenger side of the tonneau near the mirror, there is a lift a dot on the chrome door finisher just behind the quarter light. I do believe that there should be 3 tenax behind the fold down back seat squab, and along the side panels to the rear seats -
these are for the hood cover. I have just had a look at Anders Ditlev Clausager's restorers guide and it is not giving much away 'cept that there are definitely three fixings across the back one near each corner and one in the center - also reinforced by Roger Moment's book. There are no studs on the side on both books, they were on the BJ7s. There are also pop studs to hold down the flaps for when the seat belts are not passing through the tonneau.
