Interesting, I took a couple of pictures of the hinge and they seem to show
no structural connection from the side rails to my cross member ?
I am flying tomorrow so I will examine this further, but I wonder if they
varied the construction. Many of my aluminium support brackets are glued
to the shell with what looks like a black polyurethane glue, similar to
that used in the car industry to glue panels. I assumed this was the case
for this cross member.
I agree that It would be ideal to change one bolt at a time, but I was
thinking of implement Steve Koerners mod which I believe would require you
to remove both bolts to get the 1/4" spacer under the handle ?


It is riveted to the top side rails. However one US owner has found
all rivets sheared. All mine seem ok.

In any event you should only change one bolt at a time!
