Nice start! I could’ve missed it, but if it hasn’t been said, the windshield hinge screws are not a normal Phillips bit, they are a JIS spec screw head. A JIS bit will get a better/deeper grab & help keep from stripping the heads. Mine were stuck solid but after a coulple days soaking with PB Blaster, some heat from a map gas torch and a JIS bit (got off Amazon) in an impact drill, they all came right out without breaking or stripping. Another trick I found that worked well was to bump the bolt tighter first, then back it out, just one more trick to help loosen the rust bond. Good luck and have fun!
