Hello everyone.  I have an MP5 motor I am having trouble keeping it from coming out of my rear bike dropouts.  The rear dropouts are shallow however I am trying to make due.  I have 2 rear torque arms one on each side of the rear wheel.  Gary suggested I add two additional torque arms to try to prevent the wheel from coming out of the drop outs.  I am unsure of how to attach the second set of torque arms.  Below is a picture of my rear wheel with the current torque arms.  Does anyone have any suggestions or has anyone had these these problems and found a solution?  Aside from getting a new frame any help would be greatly appreciated! 
Cheers.
Jeremy
