Hey Suprafabs, The Forum members may be able to help buddy. Its hard to find guys who know these older bikes, especially well enough to know about dual disk conversions. I'm wondering if maybe some of the spacing is off? That or is the pivot arm mounted between the fender and the lower fork leg? I did that on mine and the pivot arm was at a bit of an angle. Once I moved the fender mounts to the inside, it lined up correctly....
should be fender...Pivot arm... fork leg. Hope that's all it is. Good luck buddy.
