I had a set of aftermarket fenders that I wanted to put on this bike. They were straight and needed the inset parts on the sides to clear the forks. I took them an layed them with the inside edge on my vice and tapped them with the round part of a ballpeen hammer and it put them in there perfect. didnt even mess up the paint. I measured the width of the legs on the forks and opened my vice that much . Worked pretty slick.
