I thought about getting construction paper and making a template of the wood frame but I didnt bother.
The dimensions needed can change depending upon how the lower part is mounted (because the back part is angled, the height changes how far out the RSD sits over the front lip). I made brackets to hold the bottom of mine in place and have it tilt backwards just a hair to help crap from rolling forward.
