Technically not an ad (not that I can post one anyways). 7 years ago one of the plastic pieces on my 328's pop-up headlamps linkage broke, leaving me with only one headlight. The plastic pieces only come as a part of the linkage assembly - and would you really want a piece of new old-stock plastic after almost 40 years, even if you could find them? If anyone needs a new set of those plastic pieces (the rod-ends on the adjuster), I modeled them and printed them professionally out of Nylon. They have been on the car for 7 years and 40,000 miles with no signs of distress. This is a link to the model, which is free to download and have printed in whatever way you want: https://www.printables.com/model/1312281-headlamp-lifter-assembly-adjuster-rod-ends Image Unavailable, Please Login Image Unavailable, Please Login
Mine broke also I replaced mine with metal ones left hand and right hand thread from Amazon $15.00 for 4 pcs Image Unavailable, Please Login
Replacement connecting rods aren't that hard to find: https://www.ferrariparts.co.uk/part/ferrari/61268600-a It's a new replacement part - Not an ancient original stock item, so the plastic parts shouldn't present any risk of failure any time soon
