Ive had great luck with JC Whitney. Even for rebuild parts for clutches on my 84 standard wings.
http://www.jcwhitney.com/autoparts/StoreCatalogDisplay/c-10111/s-10101I have always liked my windshields since my 76 wing. Never liked the full fairings as much till this new 1800s.
I did not like my stock valkyrie windshield at the beginning. Did like the styling. I made a custom device to change the rake angle and it was OK at best but much better.
With that said I am a function over form person, I ride my bike almost exclusively so I like comfort. I generally go several months before I use my truck. Had to recently due to the cat 3 hurricane we just got hit with in the baja a week ago.
I changed my 97 valkyrie to try this new one, it only mounts in two points so you can really change the airflow angle fast or remove it quickly, no tools to do this on the fly. It is a very small windshield but I consider it to give me better visibility and coverage in many respects. I have found anytime the windshield is cloer to you it seems much more efficient.. But I no longer hit rain, maybe two to three times a year. I really like this windshield because I can actually change the angle on the fly to horizontal when I am stuck in traffic or in a city with stoplight traffic on a hot day. I have tested it to about 100 mph for extended periods. plus really low cost. 80 bucks

These perform great in the rail, used them in Chicago area for years.
