Due to the orientation of the OEM 22lt lid if the catch is not engaged properly the lid can fly open at speed. I've seen OEM strap supports bent when this happens and I've also seen repaired and modified strap supports after having this happen.  Sometimes the locking hook is only just hooking onto the lid catch and even after checking it can still release. In order to stop this I found that by placing a  lump of plasticine in the throat of the hook and then closing the lid you can determine if the catch is fully engaging. Mine wasn't and required adjustment. As an extra precaution I added shortened card table hinges on both sides of the lid. These were mounted to pieces of plastic cutting board which were drilled and tapped and counter sunk. The easiest way to make mounts is by drilling the plastic with a hole saw. These were then glued to the inside of the lid using J B weld epoxy for plastic. I did try various other glues that didn't hold. I still occasionally ride off with the lid not fully closed and have the lid fly up but nothing is now damaged.

I reversed the hinges and put a hardware store clasp lock on it. 

bought it today and yeah,the gearbox fits straight up, tried it with my gs1150 wheel and it has less offset, will still need to machine a bit off but better, and better is good
