ok, I just got the very last 2 of the outer metal clamps from VW for you, after these 2 there are no more left anywhere in the world,
with postage to you they cost 25 euros for the pair, I collect them tomorrow & will send them onto you after christmas
I am still looking for the rubbers,
btw what diameter is the bar itself? ETKA says 13mm surely that can’t be correct?
