This template is great, everything is exact!
Cut mine out with a plasma table because i had access, and its sturdy enough i think the frame will give before it does. Added some holes for SS3’s as an after thought. Also i changed up the chain hook points.
One thing he says in the video is to brace and pay attention to warping, the only spot i had a real issue is over the license plate because i didnt brace it and it pulled in the center. But overall, i am very happy with the outcome, the template is spot on though!
