1) As delivered 1, 2010 Vespa GTS 300 Super Sans rack
2) you need a #2 Phillips and a T30 torx to install the rack
3) remove black bumpers, yes there are holes in the rack
4) slide nut brackets on to the lower clamp
5) tighten down with wavy washers under phillips screw
6) Stick rubber bumper on case (it is a lot smaller than the photo)
7) drill out the 9mm (3/8ths for me) holes and put spacers in (I put a washer on top of that)
8) mount to frame with square nuts then use lock nuts to secure (10mm deep socket)
9) Case installed
10) waiting on my light kit install now
BTW case, bracket and good karma came from the New Mgmt at Vespa boston (does not feel like a used car super store anymore)
