Delica Canada | Mitsubishi Van Club

Hi people, i need some help please. I was given this roof rack lately and was told it came from a Japanese import. It measures 1.26 x 1.6m, only the width is adjustable. Hope that helps a bit with identification. All the writing on it is in Japanese as is their website. Can any of you identify this particular model? I have a Mitsubishi L200 with roof rails on a Truckman fibre glass rear box. What feet do i need to make it fit because from looking at photos i appear to be missing the rubber/plastic feet and where do i get them. What are the adjustable parts for inside the body of the rack used to carry, I'm going to take them out? Thanking you in advance.
