Just got some parts in the mail. I still need to get some mounting hardware. I’ll be able to see the size for the side panels, but not so sure about sill to panel. Prettt sure it’s 1/4x20 but not sure on length, or type of washer if any. Also would like to know if I need to attach some type of strap to the left and right panels to support them when removing the old panel. I appreciate everyone’s help here these last weeks. I’m definitely taking more than I give. It doesn’t go unnoticed. Thank you all.
