I still have some TC5 parts so I just might give it a try. Also using front TC6.2 arms in the rear as posted by wtcc - just curious!
Pic of how you cut the servo mount piece would be nice. Might help ...
As for running front arms in the rear I'd definitely modify the shock mounting position and same for the swaybar mounting position.
Here's how I cut my servo mount, was just trying to make it look as clean as I could.
