Have you run the car yet with K diffs?
Did you have to modify the Kyosho out drives for the durango shafts to fit in?? The pin is thicker then the kyosho ones so you will need to open up the outdrivs, slots to fit..i wonder about the ball with pin through it as well.. this is bigger and maybe to tight in the outdrive..
Ive tried Durango diffs in the FS2... good but too brutal..pretty straight forward to fit, just make sure all meshing is spot on.
