I cant recommend the shifter anymore.
I had tons of issues with reverse locking out, not locking out. I spoke with someone (who will remain nameless) that designed the shifter. He no longer works for JHR. He told me it was rushed to production and it still has a few bugs in it but he no longer has the means to work on it. He offered for me to send it to him to go over to see if it was a simple fix. He gave me some suggestions that I tried with no success. I also tried to isolate it to something else. I tried swapping out the spring for reverse and basically took it in and out a few times, cut my shifter boot (had spare) to make it so it didnt pull, (The shifter is taller and sits back further resulting in the shifter boot being very tight and we thought that might be a cause to one of the many issues I had with it) and even completely removed the inner boot as well to see if the shifter was hanging up on it. I even removed the reverse lockout tab completely (Bolts on and is made out of Delrin plastic) and I still had issues getting into reverse and it popping out of gear.
So. I went back to the stock shifter and put in my spare leather boot and a GT knob I had as well. The stock shifter is what I will stick with until I can test drive a car with the MGW or Barton.
I was told to just keep the shifter and got my money back so I am not out anything except for a shifter boot I had as a spare for a project and my time.
Until they come up with a shifter boot that fits and fix the issues I would stay away.
I wanted it to work so bad. I tried everything. I loved how it raised the knob and brought it back and how firm it felt.
