I came across this post and decided to sign up and offer some help.
I finally decided it's time to replace the stock non adjustable front toe and rear camber links,.
The front toe turnbuckles are Traxxas TRA 3643.
The rear camber turnbuckles are Traxxas TRA 3644
The 3644 links have two ends that are different than the other 6 and comes with two screws. These two links need to be swapped to the longer links for the rear and installed on the shock tower.
They will bind up if you try to use these ends up front on the toe links.
Longer screws are also needed for the other 6 ends, the stock screws just aren't long enough.
These will also fit the 4x4 Ruckus and Circuit, (exactly the same)
