They didn't come with any instructions?

On mine, I just drilled 3 holes, and installed them from the bottom. This way I didn't have to remove any material from the upper tower. I use the stock holes to install the upper stress bar.
I did have to use 6" springs up front to allow for the loss of movement by installing them below the perch.
