I installed the canopy frame on my 12 just as directed. I used the wood spacer blocks to hold the rear frame to the roll bar. I put the bubble on and did the necessary trimming and proceeded to drill the holes for and aft. When I got to the point of removing the spacer blocks and clamps so I could tilt the canopy forward things changed. The canopy frame twisted not allowing me to raise it up and forward. The plexiglass is hitting on the pilot side. Should I remove the bubble and trim the forward portion of the bubble? Help. Thanks everyone.
