Okay, after a few days of delays for moving $&($%&(@%&*$ snow, I finally got to those bolts.
They loosen the latch and allow it to be repositioned, nothing more. After much fiddling, and repeatedly picking up the socket because of the $*#W*^#(^)^ COLD, I finally got two of them to move, a little. What this does, I'm not sure. It might release the lock, but I still couldn't push anything open.
At best, this is a piss poor design. I didn't want a Curtis cab in the first place, but was the only thing reasonably close. What I really wanted, is only available through dealers installation, which would have meant at least 12 hours driving.
I can take worthless windows off my laptop and install Linux, which works far better, but I'm stuck with the piss poor design of this Curtis cab.
You're right, I'm not happy.
