I have read the many posts and was trying to come to some conclusions. For the front lip is it best to leave the front lower lip on or off (91 origional style)? Are most of you using just tape or also screws and brackets for the side skirts. Finally the rear spats, has anyone had good luck with just the tape or are the screws really necessary? I have drilled a drain hole for the spats and aluminum rail/strip for sagging side skirts.
