Here is a modified RFM for the HistorX mod. http://www.mediafire.com/?bx055gmtxqc
We had to make sure everyone we race with had it exactly the same or else there would be mis-match errors. So this has the UI change commented out. Also you can delete the image that says "please restart your rfactor" and the standard UI is used.
I have also just gotten to the point of deleting all the Movie files. Including the ISI one.
