Here are some pictures I already had available to share. I can take any other specific pictures you would like to see later today.

Thanks for taking the time to look.
Those are 2 part rails with the T-nut rail bolt anchors mounted in the center of the rails, so about 10ft lbs is the tightest you want to go, just listen to the rails while you're tightening them, if you start hearing any sounds around 8 or 9ft lbs, stop there and set them all the same.
