This took me one to two weeks to get right. I startd by gutting the top plate of all the stock bellcrank parts and posts. Than found a old servo to mock the steering for clearence with the server turned 90deg. to its' stock spot. After, I drilled out holes to put bearing keepers off a stock Losi top bellcrank that were cut out. With those in place, I made some towers to run along side the bellcranks to mount the top keeper.
All this cures things like,
Bump steer.
Steering end points.
And, binding.
