Hi mikenlapaz,
Years ago Futaba did manufacture "reversed" servos for the public, but with the advent of servo reversing in the systems, there was not the call for these as there had been.
1.) We cannot offer you any assistance at all in modifying our servos in the manner that they were meant to be used, nor will we do the mofication ourselves.
2.) Our suggestion would be to look into the "servo reverser" that you are looking at, as it will offer the equal throws and adjustments that you want.
I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.
Sincerely,
Krysta
Lead Futaba Customer Service and Programming Technician
