It's disappointing that there is so much clearance between the bolts and the frame, not because the bolts should touch the frame (they should not) but because the longer that clearance distance, the more bending occurs.
The top bolts are not supposed to support the bracket by bearing against the top of the frame rail. I would place the bracket so that 1/4" of space is divided roughly equally between top and bottom, not all at the bottom; this would give the link plates a better chance of clamping evenly. Perhaps other E2 owners have noticed how their brackets are placed... and what you can get away with.
Unfortunately the installation manual doesn't address this, and all of the drawings suggest that there will be no significant clearance with the bolts in the right holes and a frame rail a whole multiple of 1/2". The frame is a full 4" tall, right?
