This is a pair of newly made Dell'Orto PHM40/AS and PHM40/AD pumper carbs that I have exchanged the new style bowls and nuts for new old stock 70s era plated float bowls and float bowl nuts, along with adding metal fuel banjos to. So, you get a pair of new clamp mount tickler/pumper carbs, but, they look like the 70s era carbs found on super sports etc......
New construction but looks more like what came on your 70s and 80s era Ducati. These are clamp on type bodies with ticklers & accelerator pumps.
And YES your original alloy top caps off any PHM carb will install directly onto these without any modification required.
Everything is 100% brand new genuine made by Dellorto.
