sway bar help

[79gmcsierragrande]

I bought a new sway bar from Summit, it’s an Addco aftermarket for truck that didn’t come with a sway bar (mine did not). I’m having trouble figuring out where it goes on my 79 Sierra Grande and the directions are nondescript. If I put it behind the tires the headers and oil pan are in the way. If I put it in front of the tires the tie rods are in the way. If anyone has one of these or even a stock one some pictures would be great. I also bought the rear but I haven’t looked at that one yet, so I’ll probably need pics of that one too. Thanks for the help.
