Look like car shockers. If so, they fit on a plate with a hole in, with 1 rubber doughnut bush either side, tightened down with the nut. (If rubber doughnuts is what the black bits at the end in question are!)
Could maybe make a clevis bracket to mount them more traditionally.
They probably mount through a strengthened bit of body panel on a Vespa?

You don't necessarily need an eyelet at the bottom, as you could screw on the bottom bracket, No2 in the picture from your old shock, hence the turn it upside down.....See
