Its a nice clip.The duetto I bought years ago from a friend had been poorly repaired from a rear hit with new sheet metal (still available 30 years ago) but I believe the underlying braces extending out from the tub were not straightened and therefore new straight metal cannot properly mount to a crooked sub frame. I think that is the cause of my issue.
I have two Alfas in front of the Duetto in the project line right now. Keep me in mind-its not a top priority for me at this time. Good luck. It looks like good material to work with
