Arrived on site Friday, got set up and then decided to light the BBQ. However when I lifted the flap to plug the gas hose in to the side of the caravan, I found one of the plastic hinge pins on the flap had completely gone and the other one was nearly out as well. I am struggling to find a replacement hinge pin. It looks like it is a piece of clear nylon about 2mm in diameter and about 20mm long. Has anyone managed to ever track one of these down? Its for the standard MPK box with a gas tap in it on a 2006 Abbey. I tried to look up MPK on the internet but could not find the company itself.
