Thanks Mike!
For the rear I suspected that the arc of the fender might be off, so I'll see if I can "influence" it to get closer.
For the front, however, I think I'm looking at needing a little more of a plan! One thought I had was that I could gain something by checking where the clip that holds the fender below the springs is mounted on the fender. The holes were pretty wallowed out and I used small diameter screws to mock it up, so maybe I can gain some height there. But the lower stays on mine are straight, not bent like yours...so I'm having difficulty envisioning the geometry of what would happen if I put that bend in it? I'm using the original mounting holes as well as the original riveted bracket ... but one was broken so it was welded back together.... but could have been stretched! I'm going to play with it again tonight.
Thanks for the great picture and ideas!
