Don'y see why the later version wouldn't work! It's just a hose from the outlet in the valance to the nozzle on the wiper arm, may need to change the outlet to a nipple on the valence - but I don't imagine that would be a major PITA.

Could be wrong though!

BTW both 1st and 2nd gen 126s over here (which were Euro design) had the same headlight wipers, I've not seen squirter nozzles on the valence.
