I am reproducing another batch of V7 Sport / 750S front signal light brackets. The stock ones used a separate screw in hollow stud 12mm x 1.25, I am making a batch if these and another bunch using the Aprilia stems (exact same length and diameter that have the threaded extension to accept the Aprilia cast signal lights.
I had the oval brackets water jet cut from 3mm plate steel and turned down 16mm tube to the correct 15mm diameter and cut in female 12 x 1.25 threads, I will be sending these off for chrome plating in a week or two.
My price per piece (each) is $40 USD. If you want some you can pm me and reserve a pair.
I may be making up another batch of the rear brackets but don't have any spare pieces right now.
The signal lights for the Euro spec are the high quality Aprilia units that Ducati used as well, a good pair of these typically sell for $100 USD if you can find them, unfortunately I don't have any extras to spare. These show up on German Ebay quite often. The orange Aprilia lens are very hard to find.
Here is a picture of the V7 Sport at the museum in Mandelo, nothing special about the bolt holding the head light
Drain plugs where chrome plated, send yours to a reputable shop to get them replated
