Original  Noma pillars. To remove old pillar pieces use a dremel 3000 set on speed 6 & a #426 cut off wheel.  To remove the base put 2 layers of duct tape on each side on the platform & grind it down. Then flip the housing over & grind away any grey plastic that's on the underside of the roof.( and wear  googles) Then use a good amount of crazy glue gel to attach the new one.
