I've got saddlemen jumbo drifters on the ez-backets. When they
started to tear, after the New Hampshire Rally, I put plexi-glass
backing plates on the inside. Solid as a rock now. I also took
a Dremel with a little grinding stone to the right side bracket.
Now it goes on/off without a block of wood and a hammer.

I'm finally happy with my set-up.
