I purchased two pieces of ½” squared steel, I clamped the middle onto my engine lifter & using 2 x 12” shifter twisted half of the bar 360 degrees clockwise. Then I did the same to the other side to make a one of a kind window spiral support bar, no doubt someone has already done this but I haven’t seen any as yet. Fabricated one end to fit on the light stands & the other to fit the top of the window support pillar.
