Fit windshield in opening and marked for trimming. Drilled six holes to fix location then trimmed approx 1/4" from top edge and 1/8 from bottom edge with dremel cut off wheel. Removed windshield and smoothed cut edges with belt sander then hand sanded to smooth edge radius.
Reinstalled with the six screws, Verified fit is now good all the way around, ready to drill remaining 25 holes.
