As said before , for the clutch head screws in the window regulator track . Pb Blaster Penetrant . If they will not move with the clutch head screw driver , lay it on something flat , put the clutch head srewdriver in the clutch head and smack it with a BFH . Try again. If it still will not come you can fit the smallest vice grip made into the channel and break them loose . It even that does not work use oxy aceytlene penetrating fluid .

To remove the sash you will have to remove the barrel screws on the end . If you do not want to save them drill them out but do not drill into in either the sash or frame . Use the right size bit . If you are trying to save them use the oxy aceytlene to gently heat them and while still hot remove . I used to do this a loct before new barrel screws were available repo .

Once the screws are removed take a short 2 x4 or 1x4 and place it on the top edge of the sash . Hit it with a BFH . The sash will pop off .

Now for the top edge as long as they used the original seating tap put a pair of gloves on . Turn the window frame upside down and hold the glass with one hand. With the hammer tap the ends of the frame . Work back and forth from one end to the other end . If your glass is not broken it may come out all in one piece. If broket like yours , it may come out in several pieces and you will have keep working . Sometimes a small screwdriver between the remainingg glass and the outer frame . You can lay the frame down on something flat (floor) and break the glass out but some will be stuck in the channel and you may still have work out with the screwdriver in the channel. Whatever you do wear safety glasses. Good luck.
