Looks like the van retains he earlier air ducting hence you have no way of relocating the wiper motor on that side

Ethel - are you saying it is possible to keep the wiper motor on the LH side and move the wiper wheel boxes to the 'LHD correct' holes in the scuttle? If so then how is that done - 'because it might be neater than moving the wiper motor. I guess it means stripping the wiper rack down and 'altering' the outer tube so the wheel boxes are located in the correct place - yes? Or is there a LHD specific outer tube or wiper rack we can buy?
