I unfortunately don't have any pictures of this. However, it looked like it was a gradual wear of the thread on the gearbox plate. The threaded holes (when they failed beyond the point at which they could hold the gearbox to our frame) were oval shaped generally in the horizontal direction. (with typical orientation of mounting) In fact, after drilling out the holes for a 1/4-20 tap, the holes were still not perfectly circular, that's how much damage had occurred. We noticed this issue right before eliminations at Fall Fiesta.

We haven't contacted WCP, but plan to do so, along with all of the other issues we have experienced with the SS gearboxes, namely with the CIM mounting.

Something with these gearboxes and oblong shaped holes

Edit: The gearbox on the other side had the same issue shortly after, and has not been repaired yet. When it is disassembled, I will be sure to post a picture, however cannot comment on the failure of it yet as I haven't seen it, it'd be reasonable to assume it is the same failure method however.
