Thanks guys my rado was booght out of a carpeted garage and owned and looked after by a vw mechanic and enthusiast who bult the fisrt road going G60 mk1 Golf in britain
and when i bought the rado she had 20 inch blade on driver side and 19 on the passenger side have changed them a few times and been automaticly suplied the same sizes by vw dealers.
But thanks for info on the arms long on passenger side makes sense
