Trac Bar question

Agree. The "arc" that the rear housing moves in isn't obvious. Depends on the leaf spring length, arc and if the front portion is stiffer than the rear part of the spring. The forces generated if the "arcs" aren't the same are unknown and can be very large. There have been failures in similar designs. However, there are lots of similar designs out there. Where I work we are doing a design that is fixed at the rear housing and uses a shackle at the frame to account for the different "arcs".
