Here are a couple more pics of the conversion. You can see the additional shims I had to use with the stock 808 center diff mount. I am swapping the 354011 XT8 mount in the car tonight, so I will only have one shim on each side. Weighed the car today without body, and it was about 7.2lbs. A nitro 808 without body was about 7.1lbs, so they are pretty close with the current equipment. The nitro car did have Crimefighters on it though, so I don't know if those are heavier than the Holeshots I had mounted.
