Just went that route with my trans. Dave at Pro Trans did mine. He also has the correct arm available if you still utilize the stock N safety switch so that it will only engage the starter in PARK and the last N only. When talking with Paul at T/A on this subject (I was buying a different gate for my pos Cheetah shifter to accommodate new trans brake) he cautioned of the danger and seemed oblivious to the fact you could make them safe.
