[Closed] Total long shot. Roof box to swap??

Recently bought a T4 camper and decided to fit a roof box we had bought and never used. Had roof bars fitted and then found that although box perfect size ( 1350 long x 1000mm wide) the opening is to the left when veiwed from the back. This is the same side as the roll out awning on the van so we would have to roll it in every time we wanted anything out of the box. Looked at swapping the locks and hinges but no go. Does anyone have a similar sized box that they would want to swap, bigger would not be a problem. Distance no object, although based N of Sheffield, I travel with my job. Only issue is it needs to be in the next 2 weeks as off on hols mid July. Help would be greatly appreciated, may consider cash adjustment if better quality than the Halfords one we have.
