Here is a potential solution for such a bracket:

1. Using aircraft grade 1 x 2 x 1/8 inch aluminum angle "iron", cut 1 piece 1
inch longer than the diameter of the govenor body.  

2. Cut another about 5 or 6 inches longer than the first piece.  

3. Align the 1 inch sides together at one end of the two pieces and clamp them
so that a 4 inch wide flat surface is formed by the 2 inch sides.  

3. At the center of this surface use a flycutter in a drill press to cut a
hole with a diameter slightly less than the govenor body diameter.

4. The remainder of the center of the 1 inch angle iron can be cut away with a
hacksaw.  Use AN3 bolts to fasten these 2 parts together, placing the holes
close to the "angle" so the tabs won't distort too much when the bracket
becomes "clamped" around the govenor (this step is best performed before the
hole is cut).

5. Cut off excess material, taper the resulting arm, drill lightening holes,
round the corners and clean up the piece.

6. Use 2 ADEL clamps on the arm to hold (tightly clamp) the govenor control
cable in position.  My cable makes a 270 degree bend to make it thru the
firewall hole which aligns fairly well with the prop control knob location in
the panel.

7. Mount the bracket on the govenor (mine is at about the 2 o'clock position
when viewed from the rear of the engine).  BTW, all this work was accomplished
with the engine off the airplane and the govenor mounted on the engine.

8. Take an AN3 bolt (1 inch?) and a 10-32 die and cut as many threads as
possible.  

a. Drill a hole longwise thru the bolt with the diameter of the govenor
control cable wire.
b. Place this bolt on the cable wire head first.  
c. Make a 90 degree bend in the end of the wire and cut off the bent end just
so the wire can be pushed into an AN3 threaded hole.
d. Thread a locknut onto the bolt.
e. Fish the wire into a female rod end (AN3) and get the bent part into the
rod end inspection hole (it may be drilled larger if the wire diameter would
require it).
e. Screw the bolt down to put some pressure on the wire end. Lock it in place
with the locknut.  The wire govenor cable should now terminate with a rod end.

9.  Use a AN3 bolt and a spacer to attach the control cable rod end to the
govenor arm.  The spacer is placed on the govenor side of the arm.  Remember
that the arm moves in and out and polarly so check all movement.

Good Luck!
