Just about every Coupe we see has play in the wiper linkages, ranging from slightly juddery to linkages dropping off the ball joints
IIRC, the entire linkage is still available at about £300 - £400, but amazingly, the black plastic sockets have never been available (despite the fact that they're the same as the Cinquecento, for which you could buy them, but sadly, the parts are now obsolete)
Anyway, after a couple of enquiries and some pestering, I've had these made....
Quality appear to be good - they are a snug fit and work well - they've eliminated all the play in my very tired mechanism
They are now available on Ebay - around £30 - £35. I tried to set up a group buy, but they didn't seem all that interested
I'll report back when I have a chance to use the wipers properly, but it looks good so far
