I am thinking of putting one of their full 10 point cages with the family (rear) addition. My questions are these does it come assembled? How do you tie it in to the frame/body? I did a search much still a little confused on these areas. I have an 88 Gmc Jimmy. I need to do the rear addition becuase my kids go with me most of the time. I really like their cages and prices. As far as the assembly goes how much came assembled if any. Thanks For any help and hopefully lots of pictures.
