Product Description
There are 4 of these on the panel which slots in vertically behind the rear seat back rests. The originals are rivetted in place, and I would suggest the same method is done to attach these.
The peg is hollow and should accept a 4mm diameter x 25mm long section of metal - eg the thread of an M4 screw to give some strength. This could be glued in place with an epoxy based adhesive.
