Sorry man. I never istalled a Kyosho dif in my xray, When I posted that I just went to my parts box and compared some spare difs I have around. I thought I grabbed a Xray to compare to the kyosho, but it must have been a Cen dif I looked at. Sorry again for the bad info. Just trying to be helpful and didnt double check my work. That and its now clear that I have way to much stuff around here to keep it all straight any more.
