Speaking of BJ7 dashpads (the upper dashpad), can anyone share their experience with what is the correct or best way to fasten the padded dashpad to the metal structure underneath? The bottom of the dashpad is made of thin plywood. The plywood is too thin to run screws up from below, and only having the two rear view mirror mounting screws holding it in place seems inadequate. Contact cement?? Or?? Final fastening of the dash pad remains one of the very few things left to do on this BJ7.
