That's never been my experience. But, every seatbelt I've seen (that wasn't a racing harness) has been attached to the body either with a hex bolt (3/4 or 7/8 inch) or a Torx-head bolt (usually either T-45 or T-50). The shoulder strap is behind the plastic body trim. Normally, you'll have to remove the door sill plate first.
