Yup that would be correct.. I would have swapped it before it was shipped and just sent the extra parts... I have looked at it and compared it to my 8-t and can't tell whats wrong with so it I swapped the center diff and now it works smooth as butter...
Reads like you swapped it with the 8-t but I could be misreading. Unless the diff kit arrived today and you installed it today before sending me the picture I requested...single picture with everything in it including the brand new diff kit. Not sure why you would do that if you could have just sold it as pictured.
I could send a picture of the 2 diff's if you look at the eBay auction it is not really a packaged diff from losi... it was out of a kit, a chop shop..
