help. One last mod I need to do...transgo 2 shift kit...

hello. how do you guys perform this mod? do u have a shop do it? a guy with a lathe? should i send it to a tranny shop, like cope or other? maybe contact trangsgo and see if they have one already made? ? i have a couple machinist friends say theyd have to make up a tool to hold it, and then machine, and saids its too much work for them....so, what do u guys think??
