Rear spare wheel holder for a 1963 VNB


I want to put a spare wheel holder on the rear of my 1963 125 VNB Vespa. The scooter has 10" wheels.

I prefer the designs which hold the wheel lower on the rear of the scooter.

SIP sell 3 different models (90955000, 100, 200) with different shaped support bars primarily for newer models of scooter. 

Which of these would best fit my scooter with the minimum of drilling?
