My main concern was how to re bend the angle of the lower frame as what was to me the correct sides were wrong given the tab to stop the latches is supposed to be on the inside. I was about 8" too far away at back of door off of tub. I had to re bend with out tearing or ripping any stitching because of the loooooong time to get my top.

This is a template I made for lower frame that had to be re bent. I cut 2x4 to match the angle of the section I had to change and put hinge to keep a good line and allow for the bend to be done at the correct point. The door is in there wrapped in drop cloth

This was the top board I put on the straight piece of lower frame that did not have to move and I had to keep it flat
