Not my cage, Dave, just some pics I was looking at online the other night. I thought it was well built, though I consider the angle of the main hoop to be a bit excessive....Structurally I suppose it's fine.

We used to run an x brace in the main hoop, but have since gone with a cross bar as pictured and a diaganol bar from the lower right to the upper left of the hoop. I'll be building a couple cages this winter, the one in the Bronco will have the rear downtubes going almost to the rear of the frame rails, and an X inside of them going to a point between the coilover crossmember and the rear of the frame.

Still trying to decide whether I will use rectangular steel or round tube moly for the frame main rails..... Be awhile til I have to decide, I guess.....
