Yeah i have a set of the steering knuckles rolling around in my toolbox already because they are the same as my truggy knuckles. I am not sure if i will have the cross pin diffs on my buggy or not. I bought it from some guy on ebay who i think got it as a b day present or something and got frustrated when he couldnt get it to run. it said he took it to a hobby shop who broke it in and tuned it up but he never ran it. there is no wear on it whatsoever and the kid even had the body on it wrong in the ebay pix haha. How long ago did they go to the cross pin diffs???
