Here a couple of pics of what I did this weekend. These are new take out seats from a medium duty GM truck.
the same kind Brian had for sale on this forum.

They have a flip up seat bottom that is kinda cool, plus the sliders are included.

I had to mount them to the roll cage due to their height, the factory flip forward brackets were to tall. I wanted to attach my seats and my but to the cage anyway. I will definately feel safer now!

I have another pair of these seats if anyone is interested, $100 obo
