hello joe,hope that helps,they should just come off with a little force,once the screws up top are out the side pillar needs to be pulled away from the frame by about a inch,thats were 3and 4 are together,its like velcro,then as you can see there is a fastener at the bottom,slide the pillar up and out with a bit of a wiggle,you will get there,good luck...........:24
