Hi, we have a 2005 Adria Coral, the cab curtain is missing and we want to fit one. There is a rail there, it's the same as the rail for the over cab curtain (which I've taken pics of). I can't seem to find the gliders to fit it, rather than have eyelets that hang down for a hook, the loop of the material goes over the glider so it's flush with the rail. Rail is 10mm deep and 6/7mm wide
