Triumph Stag Rear Seat Belt Trim

The fitting kits for Triumph Stag rear seat belts require cutting of the cubby holes. The original trim is no longer available so I thought i'd have a go at designing something to trim the cut hole.

I've left a small slit in the end of this piece so that it can pass around the seat belt and therefore does not need the belt to be unbolted for the buckle to be passed through.
