Since your fairing is similar to the mid 1970's Ducati 900SS, have a look at the way Ducati mounted it's fairings, there was a flat bracket welded onto the steering head to which was bolted the combined headlight bracket/fairing mount. This avoids the need for those large "brace" type brackets which detract from the look, and probably affect the steering lock?
There were some additional brackets mid way along the trailing "legs" of the fairing to support it there, that were mounted to the upper frame tubes, from memory. The screen, once fitted, was considered enough to brace the top "wings", but some guys made a small dia tubular "T" shaped brace that braced both wings and mounted in the middle of the steering tube top nut. Cheers, Terry.
