The Irish Mitsubishi FTO Owners Club

Hi people, i need some help please and you may be the ones to do it. I was given this roof rack lately and was told it came from a Japanese import, a van or a jeep, I don't know which, made by a Japanese company called AIBA WORKS. 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 the AIBA website. I have tried google translate but I'm afraid it is 'pigeon' english, I have also e-mailed them but no response yet. Can any of you identify this particular model? i am imagining that many such units came into this country in the past and it is only a matter of locating one somewhere. 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. Also, what are the adjustable parts for inside the body of the rack used to carry? Thanking you in advance.
