A few more holes have to be drilled along the bed rail also for the brackets that mount onto the fastrac rails which bolt on in the factory holes...
The fastrac rails 2 for each side,
The 2 brackets per side that hold the frames are drilled into the bedsides
The back frame has a tension release that tightens or losens the top... It's at the bottom and is attached to the second bracket on each side...
