It's not that hard to hook them up if you understand how they work. You have to hook them over the knob-like bolt that's on the frame. You have to clamp them to the outside of the tailgate and there is the all-important bracket inside of the tailgate.
Honestly after reading some of the other posts, I'm tempted to remove them. The gate is really heavy, but the two cables keep it from falling too far! Mine still make somewhat of a popping sound when I open and close it cause the rods are a little bent.
I would suggest trying it without the rods for a while. Removing them can be tricky - I did that recently too. I understand the some guys cut them off with a torch. I don't have a torch, so I'll just un-bolt mine and slide them out if I decide to do this.
Let me know how it comes out.
