Matt, I have a set of original instructions for installing the Vard fork on a Harley. It shows how to cut the HD springer fender among other things, they are a little rough but I will scan them and see how they come out.
Matt, I might be wrong, but I don't think that you can run the hellings and stellings bars with a flanders set up. I think the tubing on Flanders bars is round, and the Hellings is a bit ovalized. The might not fit well in the riser clamps. I tried it on one of my dads bikes and it didn't seem to fit right. Let me know how it works for you.
