I fit the windshield hoop and test fit the windshield. I cut the hoop 1.5 inches taller than what was in the plans in order to increase the headroom in the canopy. However I was not comfortable with how the windshield would have to be cut and also worried that I would not have enough canopy material if I tried to add the additional headroom. I removed and then cut the hoop 1/2 in over the plan specs. from reading others post there will be enough material for this modification.
