Go to your dealer (Guideline #8) and look at the parts fisch. Plate 129-50 shows the seat & all mounting hardware. The seat belts are on plate 118-08. Diagrams (w/o part numbers) are posted in the Tech Diagrams folder.
The belt is a fairly generic lap belt -- no shoulder harness. The buckle end is one of the types on a stiff wire so it holds it reachable rather than falling down beside the seat. That's for convenience and something like the flat plate bracket on the driver's seat buckle should suffice. Mounting is generic seat-belt stuff (which are SAE sizes, not metric) with some spacers and plastic caps for looks.
The mount is ingeneous in its simplicity but complex in production. There is a horizontal bar bolted to the fender well behind the front passenger seat. There are seat belt mount plates at the ends and a receiving catch in the middle.
The vertical frame for the seat sits upright and drops into two peg sockets in the floor. There is appropriate hardware to reinforce and water-proof the floor sockets. Depending on VW's whim the day yours was built, those may or may not have these mounts already in. The top has the matching latch for the above receiver. It has a simple pull release. Thus one places the seat frame bottom pegs into the sockets and rocks the seat toward the front to engage the catch. Release is the opposite. From the fisch, it appears the receiver bracket and belts remain in the vehicle when the seat is removed.
