There might be a bolt designed that worked better. I'd have to see it. The problem is clearance below the bolthead and in front of the bolthead.
To clarify, the #5 runner comes straight down then straight back. Imagine an "L". The bolt is right in the corner of that right angle (threads up, head down) so that an open end wrench won't get between the verticle leg of the "L" and the bolt head...that's where a smaller head might help. A boxed end would be thin enough to fit there but you can't get over the head because of the horizontal 'foot' of the "L" being too close to the top (or in this case, bottom) of the bolt head.
The right angle on the wrench allows you to reach the bolt head from the open side of the "L".
I might take a regular length wrench and a torch and bend a right angle if I can't find one.. That'll give me some more torque although, I think I got it pretty tight. The little New Britain ignition wrenches have a real good bite on the bolt heads and I was able to give it a good push from the side.
