WideGlide,,, as in from a Harley or something aftermarket? If Harley triple-tree, then most any aftermarket riser should work.
The Honda fork top bridge has rubber isolation bushings and 12mm riser mounting studs necked down to 10mm thread to prevent over-tightening. That make risers somewhat of an issue. Do NOT try drilling them for the Harley riser 1/2" bolts. You can use aftermarket ones, but need to use a 12mm adapter stud with self-locking nuts, do not over-tighten as that eliminates the rubber isolation.
