ah well. i got lucky with an experiment. on mine i was able to mill out the front section to move the frame far enough to the rear to use that hole; in return i got a comfy fit(for my taste anyway) and and less work on the front of the frame. i was able to cut it to match up with my hybrid 15* without removing alot of material
take you time and make sure you gonna like the way everything matches up. no turning back once you cut
good luck with the rest of your build
