I agree...go to upholstery supply house and buy brand new plastic pieces to go in doors and I am not sure about if they have the nails or not...I can't remember ever buying any...I believe the bottom part of most chevrolet door panels of the era do use trim screws to hold them on the door...they do on the velles and maros as I recall...if you just want to use trim screws I would consider using black ones....be aware of screw length so you don't mess up any regulator components or the windows...
