I posted y fovorite, but I have one more.
When we redid my 915 we put in a Wevo internal shift gate. It was not cheap, but worth every penny. My 915 shifts with amazing precision.......so much so I needed a new Stomski coupler and fine tuning on the shifter. Wonderful outcome.
So if you redo your 915, I highly recommend the Wevo internal shift gate.
