Sorry, didn't get that.
Do you mean that from 1996 VX had the dropping window on the left side (in driving direction, UK = passenger side, DE = driver side) or do you mean that they had it on the "wrong" side (right in the driving direction, UK = driver side, DE = passenger side)?
I already asked some sellers on ebay UK but none of them was able to tell me if they had the drop window at all.
