The graphite tie bar goes on the front hinge pins that go through the bulkhead. It keeps the bulkhead from allowing the pins to get bent sideways. Getting an aluminum bulkhead up front makes it so that the tie bar is no longer needed (as I am currently doing with my rustler).
Jay's conversion is where you take an aluminum motor plate from the Traxxas Hawk or SRT or similar and mod it to fit onto a Rustler/Pede gearbox. Only problem is that these plates are virtually impossible to find these days.
