Hmm - I planned to clamp with surfaces:
- bottom: grab the front inside the extrusion slot
- top: fix the angle on top of the alum frame
Nothing fancy, just a couple parts with holes
preventing clamping surfaces rotating and a bolt...

Did the kant-twist end fit inside the front's slot ?

Thanks,

Dave -- I am not really visulizing all this. Probably because I dealt
with it in the dark holding a flashlight. If you've worked through a
plan, it's probably a good one. It does seem like one of the jaws on
the clamp was fatter than I wished it were. So that is probably what
you are referring to. On my hinge plate, I was able to get the holes
to allign though even without the jaw stationed exactly where I wished
it would go. That might not be the case if the plate is positioned
just a little different on your trailer.
