Demon quarter flip windows

there are two...one upper and one lower..by the top and bottom of the pillar(straight piece...) drill one of them out slide the frame(like a hinge) upward.it will expose the glass on the top or bottom depending on which rivet you remove, then just carefully slide the glass out..I am pretty sure after drilling the rivet and moving the frame i removed the gasket..I know new gaskets are available as i put new ones in during my swap..Sorry no pics but you can email me here and i can walk you thru it... not too tough .... good luck...
