Cutting down a windscreen is not difficult. I recently cut 3" off a 21" Memphis Fats on a C50 and followed these directions. The only variation I did was to clamp wood blocks across the cut line after I got about 75% through with the cut to control the vibration.

Good hunting
That's the way I used to cut Lexan windshields for our racecars. Only we used duct tape on the jigsaw foot.
I've cut down 6 w/s in the last 3 years , 3 were still on the bikes, using a Harbor Freight multi-tool. Far easier to control the cut & one of the safest saws you can use. I can make a much cleaner cut to start with so finishing the edge is easier.
I've made 3 sets of lowers (1-C50, 2-950Ts) from pieces salvaged from other old w/ss. I don't even think about a jigsaw for this job any more!
